The expected value of the table is shown as below:

Step by step solution

01

Content Introduction

We are given here,

X is equal to winning amount in $

02

Content Explanation

The expected value table is:

The expected value 渭

SumofX(P)X=sumofallvaluesinthelastcolumnofabovetable=-4+0+2=-2

Therefore, there is a loss of$2on an average every time the game is played.
