Answer: There are 13 C 4 = 715 ways to choose a group of men and women.
So there are 715 - 70 = 645 ways to choose a group with at least one man.
This means the probability is 645/715 = 129/143 = 0.9020979 (so roughly a 90.20979% chance)
Step-by-step explanation: There are 13 C 4 = 715 ways to choose a group of men and women.
So there are 715 - 70 = 645 ways to choose a group with at least one man.
This means the probability is 645/715 = 129/143 = 0.9020979 (so roughly a 90.20979% chance)
