Final answer:
The calculation for P(heart disease|high cholesterol) requires the number of patients with both conditions over the total with high cholesterol, which can't be performed accurately without the specific data.
Step-by-step explanation:
The question asks about calculating probabilities related to disease cases in Santa Clara County, using probability rules, and also involves understanding the distribution of results from a cholesterol test. Without the actual frequency table or specific data regarding the cases, or the sample size and number of patients with high cholesterol and heart disease, it is not possible to accurately calculate P(heart disease|high cholesterol).
However, if this information were provided, one would divide the number of patients with both high cholesterol and heart disease by the total number of patients with high cholesterol to find the conditional probability. It is important to have the actual data to make the right calculation.
