A fraction is a way of showing a division by showing the number you are dividing and the number you are dividing by. The number you are dividing is called the numerator. It goes above a horizontal line. The number you are dividing by is the denominator and it goes below the horizontal line. When typing, a slash takes the place of the horizontal line.

A fraction is a number that is not a whole number. Instead, a fraction is a part of a whole. Fractions are equal to decimals, percentages, and ratios. They consist of a numerator, which is on top, and a denominator, which is below. The denominator represents the entire whole of the number and the numerator represents the part of it.

Goshia [24]

<u>Given</u>:

Given that in a game a player draws and replaces a card from a deck 2 times.

The possible outcomes and payouts are given.

We need to determine the expected value for someone playing the game.

<u>Expected value:</u>

The expected value for someone playing the game can be determined by

EV=(\frac{26}{52})(\$ 20)+(\frac{52}{52})(\$4)+(\frac{52}{52})(\$ 0)+(\frac{26}{52})(-\$12)

Simplifying the values, we have;

EV=(\frac{1}{2})(\$ 20)+(1)(\$4)+(1)(\$ 0)+(\frac{1}{2})(-\$12)

Dividing the terms, we get;

EV=\$ 10+\$4+\$ 0+-\$6

Adding, we have;

EV=\$ 8

Thus, the expected value for someone playing the game is $8
