There are 5 shower rooms in a club house. the probability of any of the shower rooms being empty at 5:00 pm on a particular day is 0.4 Let X be the number of empty shower room on 5:00 pm, construct a probability distribution for the situation above
I am not really sure about the notation that is needed.
but
P(N rooms empty) = $$^5C_N * 0.4^N * 0.6^{5-N}$$ where $$0\le N\le5\;\;\;and\;\;\;N\in Z$$
