$5

Step-by-step explanation:

You need to calculate the expected value of this game.

There are 4 equally likely outcomes:

1. heads-heads

2. heads-tails

3. tails-heads

4. tails-tails

The winnings for each outcome is:

1. heads-heads $20

2. heads-tails $0

3. tails-heads $0

4. tails-tails $0

Each outcome has a 0.25 probability of occurring.

The expected value is the sum of the products of the probability of each outcome and its winnings

expected value = 0.25 * $20 + 0.25 * $0 + 0.25 * $0 + 0.25 * $0

expected value = $5

To be a fair game, each play should cost $5.
