Web12.3 Probability. The probability of an event is the relative likelihood of an event, which is 0 ≤ A≤ 1 0 ≤ A ≤ 1. For P (A) =0 P ( A) = 0, the event must be impossible (i.e. the sum of 2 dice is equal to 1). For P (A) =1 P ( A) = 1, the event must be sure to happen (i.e. the sum of 2 dice is an integer). Values close to zero indicate ... WebMay 26, 2024 · Solution. There are 13 hearts in the deck, so. P ( heart) = 13 52 = 1 4.
