A sales analyst listed the probabilities of profits and losses in dollars for a certain company. Find the mean, µ for the probability distribution. x P(x)
-500 0.076
-250 0.191
0 0.265
250 0.316
500 0.152

The mean is

Step-by-step explanation:

We are given the following distribution:

P(x = -500) = 0.076

P(x = -250) = 0.191

P(x = 0) = 0.265

P(x = 250) = 0.316

P(x = 500) = 0.152

Find the mean, µ for the probability distribution.

To find the mean, we multiply each outcome by its probability. So

The mean is
