Show that the probability distribution of x satisfies the, Ask an Expert

Statistics

Suppose that the probability distribution of a random variable x can be described by the formula p(x) = x /15

for each of the values x = 1, 2, 3, 4, and 5. For ex, then, P(x = 2) = p(2) = 2/15.

A) prepare out the probability distribution of x.
b) Show that the probability distribution of x satisfies the properties of a discrete probability distribution.
c) find out the mean of x.
d) find out the variance, O2x, and the standard deviation, Ox.
