Answer:
The odds against making a free throw are: 0.1905 or 0.16:0.84
Step-by-step explanation:
The odds can be categorized into two categories
- Odds-against
- Odds-in favour
The odds against is the ratio of probability of failure to probability of success.
Given
Probability of making a free throw = P = 0.84
Probability of not making a free throw = Q = 1-P = 1-0.84 = 0.16
The formula for odds-against is:
Hence,
The odds against making a free throw are: 0.1905 or 0.16:0.84
