Answer:
Average expected chance of winning = $300
Explanation:
Average expectation to win shall be computed as follows
Chance to win = 50% of $2,000 = $1,000
Less: Chance of losing = 30% of $1,000 = -$300
Chance of losing = 20% of $2,000 = -$400
This is basically computed with the help of probability distribution provided, and adding the entire products.
Average expected chance of winning = $1,000 -$300 - $400 = $300
