Question:

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.

1. Write out the probability distribution of x.
2. Show that the probability distribution of x satisfies the properties of a discrete probability distribution.
3. Calculate the mean of x.
4. Calculate the variance, \({{\sigma }^{2}}\), and the standard deviation, \(\sigma \)
