Example 4 One card is drawn from a well-shuffled deck of 52 cards. Calculate the probability that the card will be an ace, Total number of cards = 52 Total number of aces = 4 P (getting an ace) = (𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑎𝑐𝑒𝑠)/(𝑇𝑜𝑡𝑎𝑙 𝑛𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑐𝑎𝑟𝑑𝑠) = 4/52 = 1/13 Example 4 One card is drawn from a well-shuffled deck of 52 cards. Calculate the probability that the card will (ii) not be an ace. P(we do not get an ace) = 1 – P(get an ace) = 1 – 1/13 = (13 −1)/13 = 12/13
