probability
Posted:

If there are 2 choices (doors) and 20 people choose either door 1 or door 2. What is the probability that 2 people will choose door 1 and 18 people will choose door 2. I have struggled with this for sometime now. I thought it would be simply (1/2)^20 but I am not so sure. Any Help
