1.(3 points) Suppose that during the blizzard on Saturday, January 23, 2016, a total of 500 commercial airliners were stranded at the tarmac of New York City's JFK airport. In order to be allowed to take off after the blizzard is over, each of these airliners must have less than 0.30 inches of ice on their wings.

a.(1 point) Suppose that the distribution of the amount of ice on a given airliner's wing after the blizzard follows a normal distribution with mean= 0.41 in and standard deviation= 0.07 in. What is the probability that a randomly selected airliner will have less than 0.30 inches of ice on their wings?
