How do I solve this? What is this answer?

The mean incubation time for a type of fertilized egg kept at 100.9°F is 22 days. Suppose that the incubation times are approximately normally
distributed with a standard deviation of 1 day.
(a) What is the probability that a randomly selected fertilized egg hatches in less than 20 days?
(b) What is the probability that a randomly selected fertilized egg takes over 24 days to hatch?
(c) What is the probability that a randomly selected fertilized egg hatches between 21 and 22 days?
(d) Would it be unusual for an egg to hatch in less than 20.5 days? Why?
