There are 6 girls and 7 boys in a class. A team of 10 players is to be selected from the class. What is the probability that a randomly chosen team has 3 or 4 girls?
The sample space in the problem is 6 girls and 7 boys. If ten players are to be chosen composing of three or four girls, then for 3 girls:6C3 * 7C7 / 13C 10 = 0.06993 for 4 girls: 6C4 * 7C6 / 13C 10 = 0.3671 we add the two and the answer is 0.4371
