P (k successes in n trials) = (n : k) p^k q ^n-k
n= number of trials
k = number of people in the museum
n - k = number of people not in the museum
p = probability of one person in the museum
q = 1 - p = probability of one person not in the museum

Solution Summary

The solution uses binomial probability to examine government data and determine the probability that in a group of 10, at least 8 adults have visited a museum.
