Suppose that the probability distribution of a ...
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 examples, then, p(x=2) = p(2) = 2/15
a Write out the probability distribution of x.
b Show that the probability distribution of x satisfies the properties of a discrete probability distribution.
c Calculate the mean of x.
d Calculate the variance and standard deviation.
