- ProbabilityProbability of an Event The probability of an event, denoted as P(E), is the numerical measure of the likelihood that an event will occur. It is calculated by finding the quotient of the number of favorable outcomes and the total number of possible outcomes. In symbols, n(E) P(E)= n(S) where n(E) is the number of the elements in the event and n(S) is the number of the elements in the sample space. 1. If you flip two coins, what is the probability of getting 2 heads? 2. A pair of dice is thrown, what is the probability of getting a result of prime number? 3. If a card is selected at random from a standard deck of 52 cards. What is the probability of getting a "black jack? 4. Moira collects stamps from different countries.
