A quiz team of 5 children is to be selected from a class of 29 children. There are 19 girls and 10 boys in the class. How many teams can be selected with at least 3 girls?

Answer 1

Since this is just a team of 5 students, you will use combinations to answer the question. It is the probability of at least 3 girls which means P(3 girls,2 boys) or P(4 girls,1 boy) or P(5 girls, 0 boys). Either by using the combination formula or a calculator that has the combination option, find (19 combination 3 x 10 combination 2) + (19 combination 4 x 10 combination 1) + (19 combination 5 x 10 combination 0). Your answer should be 93993
