Probability

The probability of a certain event is a number expressing the likelihood that a specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrences. In mathematics, it is a measure of how often an event will happen and is the basis of statistics.

How many numbers can be made using a 7 a 5 and a 3?

We need to know how many digits the number is and if we can allow repeats. I will do this problem assuming 3 digit numbers and allowing repeats. Then there are 3 choices for each digits and 3x3x3=27 words of length 3. If we want to consider words of length 2 also, add 9 and of length 1 add 3 and for 0, we use none of them. So there are missing details we need to be sure we are doing the problem correctly. It all depends on exactly what is being asked!

How many cards would you have to draw to be absolutely positive of getting two of the same suit?

Assuming a standard 52-card deck with 13 cards of each of the four suits, you would have to draw five cards, because the first four cards could very easily be of different suits. If four cards of different suits are drawn on the first four draws, the fifth card is guaranteed to match the suit of one of them. What is the probability of drawing four unsuited cards when drawing only four cards?

P = (52/52) * (39/51) * (26/50) * (13/49) = 0.105498199. So, the chances of drawing four unsuited cards when drawing four cards is a bit greater than one chance in ten.

How do you mathematically find probability?

find the objects area first. Then put the objects' area into a fraction by smaller in numerator and larger in denominator then divide and put decimal into fraction or percent

It helps in showcasing your expertise and knowledge on a specific topic.

What is the probability of rolling a straight of six numbers with six die on one roll?

The first die can be any number, so the chance is 1.

The second die can be any number except the number on the first one, with a chance of 5/6

The third die can be any number except the two previous ones, with a 4/6 chance of that happening.

This same process goes all the way down to your last roll, giving you:

6/6 * 5/6 * 4/6 *3/6 * 2/6 * 1/6

or:

6!/66

= 720 / 46656

≈ 0.01543

or about 1.54%

What is the probability that 2 randomly chosen binomials with integer coefficients share no common factors?

They will certainly share the factor 1. Other than that, the probability is 1: it is nearly a certainty that that they will not share another common factor..

How to Make Flowers Arrangements for Your Home?

Flowers arrangements can be a beautiful addition to any home. You will find that they can brighten up a room and be a great conversation piece. It is important that you are able to pick flowers that are going to compliment your decor as well as work well for you.

Step 1 – Considerations

You will need to first think about if you wish the flowers to be scented or not. Sometimes, strongly scented flowers can give people with sensitive noses headaches. However, you may prefer flowers that have a scent to them as they could mask odors. Leave them near a kitty litter box or a trash can to keep your home smelling fresh.

Step 2 – Time Line

Make sure that you are aware of how long these flowers will be able to last. If you need these flowers to be present for a specific day, then you may want to know how long they will be around. However, some flowers will only fully bloom after a couple of days.

Step 3 – Theme

Think of what you are going to be using these flowers for. If they are for a big occasion, then you may want to consider a more dramatic setting. However, if they are just for an everyday arrangement, then go for a look that is laid back and is not going to be too overwhelming.

Step 4 – Color Wheel

It is important that you are aware of the color choices that you pick. A color wheel is made from primary as well as secondary colors. Each section of color is going to represent an entire category. Tints, for example, would consist of a specific color, along with white. Shades would be a specific color, along with black. If you are going for tones, then you would choose a specific color, in addition to gray. As you hone your craft, you will be able to get a good feel of what works best for you.

Step 5 – Shape

There are several different shapes that you can put your arrangement in. The shape will all come down to your own specific taste and what will look best with your decor.

What is the probability of rolling 3 ones with 4 dice?

How normal distribution is better?

Normal distribution is not "better."

It is, perhaps, simpler to work with. All introductory text books and courses on statistics cover it in great detail, its properties are well-known, and there are lots of tables you can refer to.

But if the real-world situation you are trying to model does not resemble a normal distribution, then it is very bad to try to use the properties of a normal distribution or to try to force a normal distribution on your data. Doing so will give you inaccurate answers.

What is the probability of being dealt a sum of 19 in ther first two cards?

Assuming blackjack values, there are seven cards per suit that can be dealt first that could lead to a total of 19. Each of these has one card per suit to be dealt next to make 19, except an 8 has two. If it's a standard 4-deck situation, the odds are:

(6/13)(16/207) + (1/13)(32/207) = 128/2691

What is the probability of a prime number being picked randomly from the numbers 1 -49?

The probability of a prime number in a random pick from the numbers 1-49 is 15 in 49, as there are 15 prime numbers (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43,and 47) in the range of 1 to 49.
