hello I really need help with these exercises :(:(. Thank you in advance!

1. Assume that in 2008 the per capita consumption of coffee in Sweden is approximately distributed as a normal random variable, with the mean of 18.04 pounds and a standard deviation of 5 pounds.
a) What is the probability that someone in Sweden consumed more then 10 pounds of coffee in 2008?
b) What is the probability that someone in Sweden consumed between 3 and 5 pounds of coffee in 2008?
c) 99% of people in Sweden consumed less than how many pounds of coffee?
