Expected value of the money earned in the game is:

 $4

Step-by-step explanation:

In flipping a coin the probability of getting heads is 80%.

That means,The probability of getting tail  is 100% - 80% = 20%

In 10 tosses, the number of times we will get tail is:

         = 2 times

Hence, Expected value of money earned in the game = 2 × $2 = $4
