Assume that the playbook contains 9 passing plays and 13 running plays. The coach randomly selects 7 plays from the playbook.

Question

What is the probability that the coach selects at least 2 passing plays and at least 2 running plays?

Answer 1

You have a number of similar problems posted. First, can you tell us how many ways you can choose the 7 plays? This would be the denominator of your probability.

Then we can talk about the numerator.
