Probability of an event happening = Number of ways it can happenTotal number of outcomes Conditional probability is the probability of one event occurring with some relationship to one or more other events. For example: For example: Event A is that it is raining outside, and it has a 0.3 (30%) chance of raining today. In probability theory, a probability density function (PDF), or density of a continuous random variable, is a function whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihood that the value of the random variable would equal that sample. Definition: Example: An experiment is a situation involving chance or probability that leads to results called outcomes. In the problem above, the experiment is spinning the spinner. An outcome is the result of a single trial of an experiment. The possible outcomes are landing on yellow, blue, green or red.

As discussed above, for three dice the possible sums include every number from three to 18. The probabilities can be calculated by using counting strategies and recognizing that we are looking for ways to partition a number into exactly three whole numbers. For example, the only way to obtain a sum of three is 3 = 1 + 1 + 1. What is the probability that it will come up heads on the sixth flip? The correct answer is, of course, 1/2.

Probability definition is - the quality or state of being probable. How to use probability in a sentence. Solution: We learned that the probability of an event is equal to its relative frequency for a large (infinite) number of trials. Although the data above is limited, the statistician can estimate the probability based on his results. The relative frequency of the outcome 8 is simply the number 2 divided by the total number of trials of the experiment--39 in this case.
