In a survey of a group of men, the heights in the 20-29 age group were normally distributed, with a mean of 69.5 inches and a standard deviation of 2.0 inches. A study participant is randomly selected. Complete parts (a) through (d) below.

(a) Find the probability that a study participant has a height that is less than 65 inches.The probability that the study participant selected at random is less than 65

inches tall is nothing . (Round to four decimal places as needed.)

(b) Find the probability that a study participant has a height that is between 65 and 72 inches.The probability that the study participant selected at random is between 65

and 72 inches tall is nothing . (Round to four decimal places as needed.)

(c) Find the probability that a study participant has a height that is more than 72 inches.The probability that the study participant selected at random is more than 72

inches tall is nothing . (Round to four decimal places as needed.)

(d) Identify any unusual events. Explain your reasoning. Choose the correct answer below.
