Researchers at the University Of Pennsylvania School Of Medicine theorized that children under 2 years old who sleep in rooms with the light on have a 40% probability of becoming myopic by age 16. Suppose that researchers found 25 children who slept with the light on before they were 2.

a. What is the probability that 10 of them will become myopic before age 16?

b. What is the probability that fewer than 5 of them will become myopic before age 16?

c. What is the probability that more than 15 of them will become myopic before age 16?
