Answer:
Step-by-step explanation:
Given that one of the wagers in the game of roulette is to place a bet that the ball will land on a black number.
Probability will be 18/38 for black and red and 2/38 for green
We have
Colour Black Red Green Total
Number 18 18 2 38
Bet amt. 7 7 7
Win amt. 7 0 0
Net win 0 -7 -7
Prob 18/38 18/38 2/38
Netwin*p 0 -126/38 -14/38
Expected value of win = -140/38 = -3.68

1. x=2
2. x=-9
3. x=-1/3
4. p=28/3
5. m= 4
Sin(theta) = 4/5,
We will switch it to formula:
