1. The problem is to find the probability of an event, specifically 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. To calculate $P(\text{tennis})$, we need the number of times tennis was played (favorable outcomes) and the total number of trials or observations. 4. Since the problem does not provide specific numbers, the probability remains expressed as: $$P(\text{tennis}) = \frac{\text{Number of times tennis played}}{\text{Total number of trials}}$$ 5. If you provide the counts, we can substitute and calculate the exact probability. This is the general approach to finding the experimental probability of playing tennis.
