Assume that the age at onset of a certain disease is distributed normally with a mean of 41 years and a variance of 240.25 years.

a) What is the probability that an individual afflicted with the disease developed it before age 38?
probability =

b) What is the probability that an individual afflicted with the disease developed it after age 49?
probability =

c) What is the probability that an individual afflicted with the disease developed it between ages 38 and 49?
probability =

Note: Do NOT input probability responses as percentages; e.g., do NOT input 0.9194 as 91.94.
