Ann has a deck of 52 cards , made up of 4 suits, each with cards numbered from 1 to 13.If she selects a card at random, what is the probability that she selects 2 or 7 or 9 ?
Total possible outcomes = 52.ruplun wrote:Ann has a deck of 52 cards , made up of 4 suits, each with cards numbered from 1 to 13.If she selects a card at random, what is the probability that she selects 2 or 7 or 9 ?
Since there are four 2's, four 7's, and four 9's, total number of good outcomes = 4*3 = 12.
P = good/total = 12/52 = 3/13.
