What is a probability simple definition?
The ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.
Using binomial distribution with n= 15, and p = 0.40,
P(8<X<12) = P(X=9)+P(X=10) + P(X=11)
= 0.0612+0.0245+0.0074
= 0.0931
Therefore,0.0931 is the probability that at least 10 pay in cash.
