Assume that females have pulse rates that are normally distributed with a mean of mu equals 76.0μ=76.0 beats per minute and a standard deviation of sigma equals 12.5σ=12.5 beats per minute. Complete parts​ (a) through​ (c) below. a. If 1 adult female is randomly​ selected, find the probability that her pulse rate is less than 7979 beats per minute. The probability is:
