The following table shows the probability distribution for a discrete random variable.

X 24 26 27 32 35 39
P(X) 0.16 0.09 0.18 0.12 0.24 0.21
What is the mean of this discrete random variable? That is, what is E(X), the expected value of X?

Question

The following table shows the probability distribution for a discrete random variable.

X	24	26	27	32	35	39
P(X)	0.16	0.09	0.18	0.12	0.24	0.21
What is the mean of this discrete random variable? That is, what is E(X), the expected value of X?

I am not sure what do you mean by E(x), but the P(x) = X/ a constant number. So substituting for x and P(x) would definitely get you that constant. I am not sure however, hope I helped.
