Suppose that the probability distribution of a random variable x can be described by the formula P(x)

Question:

Suppose that the probability of a random variable x can be described by the formula
P(x) = (x - 3)2 / 55
for each of the values x = - 2, - 1, 0, 1. and 2.
a. Write the probability of x.
b. Show that the probability of x satisfies the properties of a discrete probability Calculate the mean of x.
d. Calculate the variance and standard deviation of x. Distribution
