In a certain city it is estimates that 40% of households have access to the internet. A company wishing to sell services to internet users randomly chooses 150 households in the city and sends them advertising material. For the households contacted:

(a) Using the normal approximation with continuity correction, calculate the probability that less than 60 households have internet access? (0.4681)

(b) Calculate the probability that between 50 and 100 (inclusive) households have internet access? Again use the normal approximation with continuity correction. (0.9599)

(c) Calculate the probability that more than 50 households have internet access? Again use the normal approximation with continuity correction. (0.9429)
