Also a 1/2 chance of picking the urn which has the other 15 pawns in, and a 7/15 chance of picking a white one thereafter. Overall probability of picking a white pawn = (1/2 * 1) + (1/2 * 7/15) = 1/2 + 7/30 = 22/30 = 11/15.

To find the probability of an event, denoted P (E), you need to find the number of possible outcomes of the experiment, n (s). This is the same as the number if elements in the sample space. You also need to find the number of ways the event can occur, denoted n (E). Then use the formula p (E) =.
