<u>0.0931</u><u>  is the </u><u>probability </u><u>that at least 10 pay in cash.</u>

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.
