Probability

Assume you have 6 spots shown below:

_ _ _ _ _ _

In the first spot, you have 6 letters to choose from. In the second spot, you have 5 letters to choose from because you already used one. Similarly, in the remaining spots, you will have 4, 3, 2, and 1 letters to choose from. So you have 6 choices * 5 choices * 4 choices * 3 choices * 2 choices * 1 choice = 720 possibilities

Neither. Because there are six sides to a die, every time you toss the die, it has a 1/6 chance of coming up 1,2,3,4,5, or 6. Plus there is an equal number of odd and even numbers, so you would have a 50% chance of getting an odd or an even number every time you roll the die.

It is a chemical compound.

The probability of drawing one ace from a deck of 52 cards is 13 to 1 as there are 4 aces in a deck of 52 cards.

The probability of then taking another ace is then 17 to 1 as there are now 3 aces in a deck of 51 cards.

The total probability for the two events in succession would now be:

(13 x 17) to (1 x 1) which is 221 to 1.

It is: 87 = LXXXVII

Yes, they do exist.

To remove a spinner from a fan, first ensure the fan is unplugged for safety. Locate the screws or clips that secure the spinner to the fan's motor shaft; these may be hidden under a decorative cover. Use a screwdriver or your hands to carefully detach the spinner, taking care not to damage any components. Once removed, you can clean or replace the spinner as needed.

Divide the total number of incidents by the total time. The result, representing the average number of incidents per unit of time, is the mean as well as the variance of the Poisson distribution.

there's 13 spades in a standard deck but since we're talkin' two decks.. there's 26 spades out of 104 cards.. so you do 26/104 which reduces to 1:4 aka the probability

It is 0.01543

The event occurred due to a combination of factors, including specific circumstances leading up to it and key decisions made by individuals involved. External influences, such as environmental conditions or social dynamics, also played a significant role. Ultimately, a sequence of actions and reactions culminated in the event, highlighting the interconnectedness of various elements at play.

Usually the doctor does not doa sonogram until you are apprx. 20 weeks along. They can, if you are lucky, find out then! But sometimes baby's do not allow them to by simply not showing them! My Dr. had no problem telling me what my daughter was and they were right! My best friend and sister are pregnant right now and are both having girls. My sister had no problems finding out what she was having but at my best friend's sonogram we were trying so hard to know and the baby had her legs X'ed in front of what we needed to see! So while there is no guarantee you will see it for sure, 20 weeks is your best bet! If not other tests can tell you for sure but they are usually only done under bad circumstances such as amniocentesis' and such. Good luck on your sonogram! Oh, and I do believe that most practices give women 2 sonograms... one around 20 weeks and one around 30 weeks or so and maybe they will tell you there if the one at 20 weeks doesn't pan out!! Pam

Probability of getting a head or tail is not equal

The first is Nominal. It is data that iscategorized and can't be arranged in an order from low to high; e.g. answer a question yes or no, colors of cars in a parking lot, race and gender. The second is Ordinal. It is data that is categorized and can be arranged in an order from low to high, but differences can not be determined, or are meaningless; e.g. grades A, B, C, D, E or grade levels 9th, 10th, 11th, 12th, or survey type questions such as do not like, somewhat like, like, love; or another is movie ratings. The third is Interval. It is the ordinal scale, but with the additional property that the difference is meaningful between the data, but does not have a natural zero starting point; e.g. the years (2009, 2000, 1610, etc), the temperature scale (50, 68, 90, oF etc). The fourth is Ratio. It is the interval scale, but with the additional property that it does have a natural zero starting point. Money and weight are examples; 0 money means you have none, and $4.00 is 2 X $2. Likewise with weight; no weight means there is none and 4 pounds is 2 x 2 pounds; the same analogy applies with height.

I'm going to assume you mean rolling the same number twice in a row in 25 rolls. The first won't cause a double, so you just need to consider the odds of rolling the same number as the last for the last 24 rolls. The easier approach is to realize that the probability of rolling at least one double is 1 minus the probability of rolling no doubles. One roll has this probability of not rolling the same as the last:

P(different number from last) = 5/6

Since they are independent events:

P(no doubles in 25 rolls) = (5/6)24

Now the final probability, of at least one double, is 1 - (5/6)24

25.

In one throw the odds are 2/8. That is, th

ere are 8 possible outcomes, two of which are considered "winning" combinations (HHH and TTT).

In 100 throws, you would expect each of the 8 outcomes to occur 12 or 13 times (the average of the number of times each of the 8 outcomes occurs will always be exactly 12.5, whether the distribution is even or whether you got all heads all 100 throws and all the other combinations were zero). You would expect the number of times you get all heads or all tails - two of those combinations - to be 25.
