5. In a supermarket, the weights of apples and pears have approximately normal distributions. The weight of apples has the mean 150 g and the standard deviation of 15 g; the weight of pears has the mean of 200 g and the standard deviation of 25 g. (a) 6. When a pear and two apples are randomly chosen, what is the probability that their total weight exceeds 540 g? (b) Assume apples cost 0.6 cent per gram and pears cost 0.5 cents per gram. When an apple and a pear are randomly chosen, what is the probability that the apple costs more than the pear? In a college, 400 students are graduating this semester. According to the school
