The mass of potatoes sold loosely in a supermarket bin are normally distributed with a mean of 372 grams and a standard deviation of 6.3 grams. The bin contains 164 potatoes. (a) How many of the potatoes in the bin are expected to have a mass of 380 grams or more? Round your answer to the nearest whole number. (b) What percent of the potatoes in the bin are expected to have a mass of less than 360 grams? Round your answer to the nearest tenth of a percent. (c) What is the probability that a potato randomly selected from the bin will have a mass of at least 370 grams? Round your answer to the nearest tenth of a percent. 3. A and B are two events. P(A)=0.45, P(B)=0.2 P(A and B)=0.65
Are the events independent?
