There are 7 students in a class: 5 boys and 2 girls. If the teacher picks a group of 4 at random, what is the probability that everyone in the group is a boy?

Respuesta :

that would be likely to happen

Answer:

1/7

One way to solve this problem is to figure out how many different groups there are of only boys, then divide this by the total number of groups you could choose. Since every group is chosen with equal probability, this will be the probability that a group of all boys is chosen.
