"If it is a black card, she wins $2."
-26 cards worth $2 each = $52
"If it is a red card between or including 3 and 7, she wins $10."
-3,4,5,6,7 = 5 cards per red suit = 10 cards worth $10 each = $100
"If it is a red face card, she wins $25"
-J, Q, K, A = 4 cards per red suit = 8 cards worth $25 each = $200
"and if it is a black jack, she wins an extra $100. "
- 2 cards worth bonus $100 each = $200
"Find the expectation of the game."
