WebTo find the probability of an event happening we use the formula \text {Probability}=\frac {\text {number of desired outcomes}} {\text {total number of outcomes}} Probability = total number of outcomesnumber of desired outcomes For example, Let’s look at the probability of getting an even number when a die is rolled. Web"The probability of A or B equals the probability of A plus the probability of B minus the probability of A and B" Here is the same formula, but using ∪ and ∩: P(A ∪ B) = P(A) + P(B) − P(A ∩ B) A Final Example. 16 people study French, 21 study Spanish and there are 30 altogether.
