The following table shows the probability distribution for a discrete random variable.
x 13| 16 |17| 21| 23| 25 |26 |31
p(x) 0.07 |0.21| 0.17| 0.25| 0.05| 0.04| 0.13| 0.08
what is the mean of this discrete random variable. that is, what is e(x), the expected value of x?

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
