a. at least one buys their dog holiday presents

b. three or more buy their dog holiday presents

c. at most three buy their dog holiday presents

d. find the expected number of persons, in the sample, who buy their dog holiday presents.

e. find the standard deviation of persons, in the sample, who buy their dog holiday presents.
