The game of heads up is played by flipping two coins. The game is a fair game
Solution:
Given that , the game of heads up is played by flipping two coins.
If they both land heads up, you win $8.
And If only one lands heads up, you win $14.
And If no coins land heads up, you win $0.
We have to pay $6 to play the game each time the coins are flipped,
Then we have to find is the game a fair game
Now, we say a thing is fair if it is favorable for us.
From players view, to say the game is fair, we have to get money.
Now, if we see
When we pay $6, we will lose it only when no heads are up as we get $0 in that condition.
But we will get 14 – 6 = $8 when one head turns up and 8 – 6 = $2 when both heads are up.
Now, number of outcomes for losses = 1 (tail – tail condition)
Probability =![\frac{1}{4}](/tpl/images/0395/0842/0d86b.png)
And number of outcomes for winnings = 3 (head - tail, tail – head and head – head conditions)
Probability =![\frac{3}{4}](/tpl/images/0395/0842/f11e3.png)
Clearly we can say that, chances of winnings are more.
Hence, it is an fair game.

Step-by-step explanation:
Divide the figure into 2 parts:
Figure 1 = 3m*5m = 15m^2
Figure 2 = 2m*1m = 2m^2
Add them: 15+2 = 17m^2
Hence, area is 17m^2
