1. The problem is to find the probability of playing tennis, denoted as $P(\text{tennis})$. 2. The formula for probability is: $$P(\text{event}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$$ 3. Without specific numbers for how many times tennis was played and the total number of trials, we cannot compute a numeric answer. 4. The probability remains expressed as: $$P(\text{tennis}) = \frac{\text{Number of times tennis played}}{\text{Total number of trials}}$$ 5. Please provide the counts to calculate the exact probability.
