Angle B = 67
The data collected from the actual game experiment is:
Win: 8 times
Lose: 40 times
Total trials: 48 times
Therefore, the probability that you will win when you play this game is:
WIN = 8/48
= 1/6 or 0.1667 = 16.67% chance of winning
LOSE = 40/48
= 5/6 or 0.8333 = 83.33% chance of losing.
