A continuous random variable is normally distributed. The probability that a value in the distribution is greater than 47 is 0.3085. Find the probability that a value in the distribution is less than 47.

A random number generator picks a number from 6 to 65 in a uniform manner. Round answers to 4 decimal places when possible. The mean of this distribution is   . The standard deviation is   . The probability that the number will be exactly 48 is    P(x=48)=P(x=48)=   . The probability that the number will be between 17 and 22 is    P(17<x<22)=P(17<x<22)=   . The probability that the number will be larger than 50 is    P(x>50)=P(x>50)=   . P(x>24∣x<57)=P(x>24∣x<57)=   . Find the 21st percentile.   Find the minimum for the upper quarter.

The duration of a professor's class has a continuous uniform distribution between 50.0 minutes and 52.0 minutes. If one class is randomly selected, find the probability that the professor's class duration is between 50.4 and 51.8 minutes.P(50.4<X<51.8)
