Question 1157680: A physical fitness association is including the mile run in its secondary-school fitness test. The time for this
event for boys in secondary school is known to possess a normal distribution with a mean of 460 seconds and a
standard deviation of 50 seconds. Find the probability that a randomly selected boy in secondary school can run
the mile in less than 451 seconds.
