Here is the problem:
The company Ali works for allows her to invest in her
choice of 10 different mutual funds, 6 of which grew by
at least 5% over the last year. Ali randomly selected 4
of the 10 funds in which to invest. What is the
probability that 3 of Ali’s funds grew by 5%?
I believe that it has to do with combinations, not permutations. I started by labeling the different mutual funds abcdef ghij. a-f are atleast 5%, g-j are not. I believe you can assume g-j are as good as 0% growth but I'm not sure on that. I do not know what to do next. What is the process to solve this?
