Answer:

$13.16

Explanation:

For each individual spin, there are two possible outcomes:

- There is a 1 in 38 chance of winning $175.

- There is a 37 in 38 chance of losing $5.

The expected value for each spin is the sum of the products of each outcome by their respective probability.

In 50 spins, the expected value is:


E(50) = 50*(175*(1)/(38) -5*(37)/(38))\\E(50)=-\$13.16

You can expect to lose $13.16 if you spin the wheel 50 times.
