In a survey of a group of men, the heights in the 20-29 age group were normally distributed, with a mean of 69.4inches and a standard deviation of 4.0inches. A study participant is randomly selected.

Find the probability that a study participant has a height that is less than 65inches.

The probability that the study participant selected at random is less than 65inches tall is nothing .(Round to four decimal places as needed.)
