5. In a particular country on the African continent, 35% of the population is estimated to have at at least one smart phone. If a small sample of 40 people is selected from the population for a statistical investigation, Use the Binomial distribution to estimate the probability that, the number of people in the sample that have at least one smart phone is; a) at most 15; b) more than 12 but fewer than 18; c) exactly equal to the mean of the distribution
