What is the probability of getting a picture card in deck of 52 cards?
There are 12 picture (or face) cards in a standard deck of 52 cards. The probability, then, of drawing a picture card is 12 in 52, or 3 in 13, or about 0.2308.
Oh, dude, let me break it down for you. So, since the first digit can't be 0 or 1, we have 8 options for that first digit. After that, we have 9 options for the next digit, then 8 for the next, and so on. So, it's like 8 x 9 x 8 x 7 x 6 x 5 x 4. Crunch those numbers and you get the total number of 7-digit phone numbers that can be formed without repeating any digits.

How to find the missing number if median is given?
The median is the middle number. If there is an odd number of numbers in the set, the median is the middle number, and the only way to find the missing number is if the median is the missing number. If there is an even number of numbers in the set, the median is the average of the two middle numbers, and the only way to find the missing number is if the median is one of those two numbers. If it is, you can take the median and the one of the two numbers you know. Use the formula (# +#)/2=median and solve.
What is the se mean and tr mean in statistics?
In statistics, the SE mean refers to the standard error of the mean, which is a measure of the variability of sample means around the population mean. It is calculated by dividing the standard deviation of the population by the square root of the sample size. On the other hand, the TR mean is not a standard statistical term. It's possible that it could be a typo or abbreviation for another concept, but without more context, it's difficult to provide a precise explanation.
0.02 level of significance what is the critical value?
The critical value for a 0.02 level of significance, denoted as α = 0.02, in a statistical test corresponds to the point on a distribution that separates the critical region (rejection region) from the non-critical region. To find the critical value, you would consult a statistical table or use a statistical calculator based on the specific test you are conducting (e.g., z-table, t-table, chi-square table). The critical value is chosen based on the desired level of significance, which represents the probability of rejecting the null hypothesis when it is actually true.
How many 3 digit numbers contain the digit 3 at least once?
172
==============================
Another contributor was amazed:
Wow ! That's a neat little problem.
Let's see . . . . .
-- There are three ways to have a single 3 in the number: 3xx, x3x, and xx3.
For 3xx, there can be 81 different numbers. (2nd and 3rd digits can't be a 3. 9x9=81.)
For x3x, there can be 72 numbers. (1st can't be 0 or 3. 3rd can't be a 3. 8x9=72.)
For xx3, there are also 72. (1st can't be 0 or 3. 2nd can't be a 3. 8x9=72.)
So far, we have 81+72+72 = 225 possibilities, with a single 3 in each one.
-- There are three ways to have two 3s in the number: 33x, 3x3, and x33.
For 33x, there can be 9 different numbers. (3rd digit can't be a 3.)
For 3x3, there can be 9 numbers. (2nd digit can't be a 3.)
For x33, there are 8 numbers. (1st digit can't be a 0 or a 3.)
So we have 9+9+8 = 26 more possibilities.
-- There is only one way to have three 3s in the number: 333.
That's one more possibility.
So the total number of 3-digit numbers where at least one of the digits is a 3 is
225 + 26 + 1 = 252 all together.
What do you call 14 digit number?
A 14-digit number is typically referred to as a "14-digit number." In mathematics, numbers are generally identified by the number of digits they contain, such as a 3-digit number, 7-digit number, etc. In computing, a 14-digit number may also be referred to as a "14-digit integer" or "14-digit numerical value."
What is the probability of 6 any numbers in lottery of 40 numbers?
Assuming there are six numbers drawn out of the set from 1 to 49, without replacement:
There are 15 out of 49 of these numbers that are prime. So the probability would be
(15 - 9)! / (49 - 43)! = (15 * 14 * 13 * 12 * 11 * 10) / (49 * 48 * 47 * 46 * 45 * 44)
= (24325271111131) / (27335172111231471) = (5 * 13) / (8 * 3 * 7 * 23 * 47)
= 65 / 181608

Can you make all the numbers up to 100 using 1 2 3 4?
Yes, you can create all numbers from 1 to 100 using the numbers 1, 2, 3, and 4 along with basic mathematical operations. This includes addition, subtraction, multiplication, division, exponentiation, and concatenation. It requires creative combinations and sequences of these numbers and operations to generate each desired number within the range.
How many four digits numbers can be formed out of 56789 if no digits can be repeated?
To form a four-digit number without repeating any digits from 56789, we need to choose 4 different digits out of the 5 available. This can be done in 5 choose 4 ways, which is equal to 5! / (4! * (5-4)!) = 5 ways. Therefore, there are 5 four-digit numbers that can be formed out of 56789 without repeating any digits.
Oh, dude, those numbers represent bust, waist, and hip measurements. So, technically, it's like a 34-inch bust, 24-inch waist, and 35-inch hips. But hey, who's counting? Just numbers on a tape measure, am I right?
Using all digits 1230 without repeating any digit how many four- digit numbers can you write?
Oh, dude, I mean, like, there are 4 digits in 1230, right? So you can totally make 4-digit numbers by using each of those digits once. That's like, 4 factorial, which is 24. So, you can totally write 24 different four-digit numbers using 1230 without repeating any digit. Easy peasy!
How many digits are there in the numbers 1 to 99?
Oh, what a delightful question! If we take a look at the numbers from 1 to 99, we'll find that they have a total of 189 digits. Each number from 1 to 9 has one digit, numbers from 10 to 99 have two digits each. Just imagine all those lovely digits coming together to create a beautiful numerical landscape!
What is grouped ungrouped data please explain?
grouped data is data which has been grouped: eg: 0-5, 6-10 ... if this was ungrouped data it would be written as a list of numbers: eg: 1,3,4,5,7,9 etc. If you search 'what is grouped and ungrouped data' google, it explains it in the first link labelled: 'Grouped vs. Ungrouped Data How To Group Data' first page. hope this helped. Maria, 15.
What is 371 to the nearest 10?
Oh, dude, 371 rounded to the nearest 10 is 370. You know, just chop off that pesky little 1 at the end and call it a day. It's like giving your number to someone at a party but then realizing you're not really feeling it, so you just round down and move on.
Difference between hydro test and hydrostatic test?
A hydro test is a type of pressure test that involves filling a vessel or system with water and pressurizing it to ensure it can safely hold the intended pressure. On the other hand, a hydrostatic test is a specific type of hydro test that involves using water as the test medium and pressurizing the system to a specified pressure for a set period to check for leaks or structural weaknesses. In essence, a hydrostatic test is a subset of hydro tests, with the key difference being the use of water as the test medium and the specific test parameters involved.
If you mean 'ephphatha' then it is the Aramaic word for the command 'Be opened'. You'll find it in Mark 7:34 where Jesus literally opened the ears and tongue of the deaf and dumb man.

Who would win in a brachiosaurus vs apatosaurs fight?
In a hypothetical fight between a Brachiosaurus and an Apatosaurus, the Brachiosaurus would likely have the advantage due to its larger size and longer reach with its neck. Brachiosaurus had a longer neck and taller body, giving it an advantage in reaching and striking its opponent. However, it's important to note that such a fight would not have occurred in reality as these two dinosaurs lived in different time periods.
