Probability is the chance that something will happen, there are two kinds of probability, theoretical and experimental. Theoretical probability is based on a sample or repeate…d trials of the experiment. The experimental probability is given by: OR Theoretical probability: When all outcomes are equally likely the theoretical probability of an event is the ratio of the number of favorable outcomes to the number of possible outcomes. In math the definition for probability is: a numerical measure of the likelihood of occurrence of an event. EX. You want to take a blue marble from a bag containing 1 blue marble and 5 red marbles is 1 in 6 or 16.667%. Probability is the likelihood that something will happen. The likelihood that something will happen Probability is a number that describes how likely it is that acertain event will occur. (MORE)

The probability of you understanding this answer is slim... does that help?? That is how you use it in a sentance. ** Jeez, that's mean, and OP, check out people who h…ave the same exact question as you on here.. "What is probability" rather than how. (MORE)

The probability of event A is the number of ways event A can occur divided by the total number of possible outcomes. For example, the number of ways you can role a singl…e die is 6, the number of ways to get an even number (2,4, or 6) is 3. So the probability of an even number is 3/6 or .5 (MORE)

Example of probability is if you have 10 blue gumballs 5 pink gumballs and 3 orange gumballs the answer is 10 because the more gumballs you have is the one you will pick witho…ut looking if you still dont understand please comment below,thanks for all questions:) (MORE)

Number of useful outcomes over number of possible outcomes and simplify it if you can. Imagine you want an even number and you roll a die. There are 6 possible outcomes and th…ree of them are useful outcomes (outcomes we want). 3 6 Simplify it and you get 1 2 (MORE)

Probability is the chance of an event occurring. For example when flipping a coin you have a 50% chance that it will land on heads and a 50% chance that it will land on tails …since there are only two possibilities. Conditional probability refers to when one event is dependent on another event occurring. It can also be written as the probability of an event B occurring after event A has already occurred. The notation for conditional probability is P(B|A). (Note: this does not mean B divided by A but probability of B after A) When two events are dependent, the probability of them both occurring is: P(A and B)=P(A)P(B|A) So for example: 53% of residents have home owners insurance. Of them, 27% has auto-insurance. If a resident is selected at random, what is the probability they with have both insurances? Let H stand for home owners insurance = 53% or 0.53 Let A stand for auto insurance = 27% or 0.27 P(H and P)=P(H)P(A/H) =(0.53)(0.27) = 0.1431 So the probability of residents have both home owners and auto insurance is 0.1431 or 14.31% (MORE)

Probability tells you the chance that something will happen. For example: There are 3 red tiles, 5 green tiles and 2 pink tiles in a bag. What is the probability of picking a …red tile? First you find out how many red tiles there are. There are 3 red tiles. Then, you add up all the tiles. Altogether there are 10 tiles. So, there is a 3/10 probability that you will pick a red tile.

The probability of not a is the same as the complement of a, which is found by subtracting the probability of a from one (i.e., P(not A)=1-P(A)).
