From the 12 male and 11 female sales representatives for an insurance company, a team of 3 men and 4 women will be selected to attend a national conference on insurance fraud. in how many ways can the team of 7 be selected?

Do you know, what permutations and combinations are? If so, you will have to use combinations for this problem.

First, add 12 males+11 females = 23 total
Then, use your combination, 23C7= 245,157
There are 245,157 ways that a team of seven can be selected. Let me know if you don't know what combinations are in mathematics.
