Say you had 100 people in the sample. 22 of them died of heart disease. 33 of the patients had one parent with heart disease. 32.7% of them died. So 32.7% of 33 is 11ish. That means 2211=11 people who died who did not have parents with heart disease which is about 10%.

11 is about 10% of 100, I meant to say. Which is the answer.
