Essay

About 40% of the general population donate time and energy to community projects.
Suppose 15 people have been randomly selected from a community and each asked
whether he or she donates time and energy to community projects. Let x be the number
who donate time and energy to community projects. Use a binomial probability table to
find the probability that more than five of the 15 donate time and energy to community
projects.
