A random variabie toliows the normal probablity distribution with a mean of 100 and a standard deviation of 10 . Detormine the probability for a randomiy selected value trem this population in parts a through d below. a. What is the probablity that the value is less than 75 ? The probobitity that the value is loss than 75 is (Round to four decimal places as needed.)
