Mean of distribution questions?


Suppose that X is the number of hours that the conference room is used per day. The table below is the probability distribution for X. What is the expected value of X, that is, what is the mean of its distribution?


X 0 1 2 3 4
Probability 0.2 0.2 0.4 0.15 0.05

for any discrete random variable the expectation is:

E(X) = 渭 = 鈭憍 * P(X = x)


E(X)
= 0 * 0.2 + 1 * 0.2 + 2 * 0.4 + 3 * 0.15 + 4 * 0.05
= 1.65

E[X] = 鈭?x_i 鈰?Prob(x_i).

You do the arithmetic.
