    Probability is a measure of the expectation that an event will occur or a statement is true

    Define probability. The probability of an event, P(E), is the fraction of times you can expect E to occur, given P. The formula for P(E) = (Number of favorable outcomes "n(E)") / (Total number of outcomes "n(S)"). Define your variables. For this example, let's say you have a pair of dice. You want to find the probability that the sum of the numbers facing up is 7. S (sample space) = set of all pairs of numbers 1 through 6, n(S) = 36. E (event or outcome) = [(1,6), (2,5), (3,4), (4,3), (5,2), (6,1)], or n(E) = 6. Calculate the probability. n(S) = 36 and n(E) = 6. 6/36 = 1/6. That is, the probability of rolling dice and having the sum equal 7 is 1/6 or 16.7 percent
