A random number generator picks a number from 4 to 56 in a uniform manner. Round answers to 4 decimal places when possible.

1. The mean of this distribution is


2. The standard deviation is


3. The probability that the number will be exactly 7 is P(x = 7) =


4. The probability that the number will be between 11 and 43 is P(11 < x="">< 43)="">
