What is the probability that you make exactly 8 sales?
Homework Equations
The Attempt at a Solution
I was wondering why 70% would be used as the the probability for the event of interest... I thought the probability would be the probability of ONE listing that would sell and not 7/10 of your listings. Can someone explain?
