Look at the photo 6 and 7 I cant figure out

  6. 1.90

  7. 1.90

Step-by-step explanation:

The expected value of winning the game is the sum of the products of the amount won and the probability of winning that amount.

6. Expected winnings = $1.00 × 0.40 + $5.00 × 0.20 + $10.00 × 0.05

  = $0.40 +1.00 +0.50 = $1.90

The expected gain for the player is 1.90.

__

7. We know from problem 6 that the expected gain is $1.90. In order for the expected gain to be zero, the cost of the game must be $1.90 with probability 1.

The game is fair if the cost to play is 1.90.
