PROBLEM:A certain AP® Statistics teacher is feeling generous one day and decides that each student deserves some extra credit. The teacher assigns each student a random extra credit value between 0 and 5 (decimals included) by using 5*and on the calculator. Let Y = amount of extra credit for a randomly selected student. The probability distribution of Y can be modeled by a uniform density curve on the interval from 0 to 5.

PROBLEM:

A certain AP® Statistics teacher is feeling generous one day and decides that each student deserves some extra credit. The teacher assigns each student a random extra credit value between 0 and 5 (decimals included) by using 5*and on the calculator. Let Y = amount of extra credit for a randomly selected student. The probability distribution of Y can be modeled by a uniform density curve on the interval from 0 to 5. Find the probability that a randomly selected student will get more than 3 points of extra credit.
