(d) What is the probability that neither Sam nor Abby is chosen?

11.)(1 point) A study of 12,000 able-bodied male students at the University of Illinois found that their times for the mile run were approximately Normal with mean 7.11 minutes and standard deviation 0.74 minute. Choose a student at random from this group and call his time for the mile Y.

(a) Write the event "the student could run a mile in more than 5.63 minutes" in terms of the value of the random variable Y. Use the symbols "<" or ">" as appropriate to indicate the bounds on Y.
