Question 587077: Suppose the chances of picking up a cold from someone by shaking hands with them is .01 (assuming you dont know whether they have a cold or not), and that each encounter you have is independent of another.
Suppose you shake hands with 5 people in a given day. What is the probability that you dont pick up a cold from any of these people?

------
Binomial with n=5 ; p(catch) = 0.01 ; p(don't) = 0.99
----
P(x = 5) = 0.99^5 = 0.0503
