Here's how to solve the problem:
Step 1: Determine the proportion of patients who die from the first myocardial infarction (MI).
If two-thirds of patients survive their first MI, then the proportion who die from it is:
1−32=31
Step 2: Determine the proportion of patients who survive the first MI but die within 10 years.
- The proportion of patients who survive the first MI is 32.
- Of these survivors, 31 live 10 years. This means the proportion of these survivors who die within 10 years is $1 - \frac{1
