Since this question deals with the number of times a result will happen, I tried to use a Poisson Distribution, but I'm having trouble separating the problem into mutually exclusive events.
I wrote a program to do a simulation and found that P(20,7) ≈ 0.058, so please make sure your answer fits with this result.
Thank you for your help!
