In his MTH173 class, Professor Fibonacci found that the mean score of the first test was 67. Suppose that the scores are normally distributed with a standard deviation of 13 points. What is the probability that a randomly selected score is less than 66? P(x < 66) = %3D What is the probability that a randomly selected score is more than 70? P(r > 70) - what is the probability that a randomly selected score is between 66 and 70? P(66 < a < 70) -
