A student's score on a particular calculus final is a random variable
with values of [math][0,100][/math], mean 70, and variance 25.
- Find a lower bound for the probability that the student's score will fall between 65 and 75.
- If 100 students take the final, find a lower bound for the probability that the class average will fall between 65 and 75.
