Your answer is incorrect.
Dr. Wong is a veterinarian who sees only dogs and cats. In each appointment, he may or may not give the animal a vaccine. The two-way frequency table summarizes Dr. Wong's 60 appointments last week.
| | Dog | Cat |
|---------------|-----|-----|
| Vaccine | 13 | 17 |
| No vaccine | 21 | 9 |
Let **no vaccine** be the event that a randomly chosen appointment (from the table) did not include a vaccine.
Let **cat** be the event that a randomly chosen appointment (from the table) involved a cat.
Find the following probabilities. Write your answers as decimals.
(If necessary, consult a [list of formulas](#).)
(a) \( P(\text{no vaccine}) = \_\_ \)
(b) \( P(\text{cat and no vaccine}) = \_\_ \)
(c) \( P(\text{cat} \mid \text{no vaccine}) = \_\_ \)
