The probabilities are given as follows:
3. P(rides bus|owns a car) = 1/3.
4. P(red|organic) = 3/5.
How to calculate a probability?
The probability of an event in an experiment is obtained as the number of desired outcomes of the experiment divided by the number of total outcomes of the experiment.
For item 3, the outcomes are given as follows:
- Desired outcomes: rides bus and owns a car -> 8 people.
- Total outcomes: owns a car -> 24 people.
Hence the probability is:
P(rides bus|owns a car) = 8/24 = 1/3.
For item 4, the outcomes are given as follows:
- Desired outcomes: red and organic -> 18%
- Total outcomes: organic -> 30%.
The error was in identifying the total outcomes, and the probability is:
P(red|organic) = 18/30 = 3/5.
