Answer: 305 people
Explanation:
The total number of people sampled is:
= 71 + 22 + 27 + 83
= 209
Out of this 209, the number of people who prefer Vanilla and cookie dough ice cream is:
= 71 + 27
= 98 people
In a sample of 209 people, 98 people would prefer either vanilla or cookie dough. In 650 people, that number would therefore be:
= 98/ 209 * 650
= 305 people
