So here's the problem:

A five-sided die has the numbers 1-5 on each side. What is the probability, after 6 rolls, of rolling a 1 or a 2 four times only?

I could do the problem if:

It only dealt with one side of the die instead of two

It didn't specifically ask for four times, but the probability of a 1 or a 2 occurring at all.

Thank you so much!
