3.22 let x have the following probability distribution: f x x x x x x ( ) = −             = − ( ) 3! ! 3 ! 1 3 2 3 , 0, 1, 2, 3 3 a. find the cdf of x. b. find the probability that x is odd. c. find the mean of x. d. find the variance of x.

it’s the first one your welcome

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94

where are the graphs?
