Do you mean the joint probability P(6–15 and prefers basketball) or a conditional probability (e.g., P(6–15 | prefers basketball) or P(prefers basketball | 6–15))?
- For the joint probability P(6–15 and prefers basketball): the denominator is the total number of people in the survey (the grand total). So
P = (number aged 6–15 who prefer basketball) / (total number of people).
- For P(6–15 | prefers basketball): the denominator is the total number of people who prefer basketball.
- For P(prefers basketball | 6–15): the denominator is the total number of people aged 6–15.
If you post the table or the counts, I can compute the exact probability.
