Answer:

3.1

Step-by-step explanation:

In order to solve for this expected value, you need to do:

(0*0.3)+(1*0.15)+(2*.27)+(3*20)+(4*.13)+(5*.10)+(6*.07)+(7*0.3)+(8*0.2)

Meaning that it is:

0+.15+.54+.6+.52+.5+.42+.21+.16

Which equals to: 3.1

Also: Feel free to correct my answer by any means, I feel like I got some parts wrong.

Answer:

The answer is, 3.1

Step-by-step explanation:

Definition of probability distribution:

A probability distribution is a statistical function that describes all of the potential values and probabilities for a random variable within a particular range.

To find this predicted value, you must do the following:[tex](0*0.3)+(1*0.15)+(2*.27)+(3*20)+(4*.13)+(5*.10)+(6*.07)+(7*0.3)+(8*0.2)[/tex]

That is to say, it is:

[tex]0+.15+.54+.6+.52+.5+.42+.21+.16[/tex]

3.1 is the value of the random variable.
