Let X be the random varibale corresponding to the value of t

Let X be the random varibale corresponding to the value of the roll. Recall that E(X)==3 and SD(X)= =sqrt(2).

a) You roll the die once. Calculate P(X)4.

b)You roll the die 16 times(this is a sample from your random variable X), let sub x be the average of those 16 rolls. Calculate P( sub x 4)

c) You roll the die 25 times. Calculate P( sub x4)
