1. The amount of pyridoxine (in grams) in a multiple vitamin is normally distributed with mean = 110 grams and standard deviation = 25 grams. What is the probability that a randomly selected vitamin will contain between 100 and 110 grams of pyridoxine?

2.The on-line access computer service industry is growing at an extraordinary rate. Current estimates suggest that 73% of the home-based computers have access to on-line services. Suppose that 10 people with home-based computers were randomly and independently sampled. Based on the Binomial probability distribution, determine the probability that 4 of those sampled currentlyhave access to on-line services.
