question
find the probability that a randomly chosen person takes public transit to work given that the person does not support the environmental bill.
| people | drive to work | walk to work | public transit to work | total |
|---|---|---|---|---|
| do not support bill | 20 | 3 | 10 | 33 |
| total | 25 | 33 | 30 | 88 |
give your answer as a fraction.
provide your answer below:
Step1: Identify relevant counts
We need the number of people who do not support the bill and take public transit (10) and the number of people who do not support the bill (33).
Step2: Apply conditional probability formula
The formula for conditional probability \( P(A|B) = \frac{P(A \cap B)}{P(B)} \). In terms of counts, this is \( \frac{\text{Count}(A \cap B)}{\text{Count}(B)} \). Here, \( A \) is "takes public transit" and \( B \) is "does not support the bill". So we calculate \( \frac{10}{33} \) (10 and 33 have no common factors other than 1, so it's already simplified).
