a) Yes, it is binomial experiment because 18-34 years olds are selected randomly and indepenednt of each other, and the probability of selecting the samples are constant from trial to trial. , and there are only two outcomes , i.e. contribute to household expenses and do not contribute to household expenses.
b)
The Probability that none of the fifteen 18 -34 year olds living with their parents contribute to household expenses is
Since the probability is very low , we would ask about the results of the Pew Research Study, to check, whether there is any baisedness in collecting data .
