In how many ways can at least 2 fruits be selected from 4 fruits?

Answer and explanation

Correct answer: 11

The phrase “at least 2” includes selections of exactly 2, exactly 3, or exactly 4 fruits. Since the order of selected fruits does not matter, use combinations: C(4,2)+C(4,3)+C(4,4)=6+4+1=11. Therefore option C is correct. A complementary method confirms the result. Four fruits have 2^4=16 total subsets, including the empty selection and the four selections containing exactly one fruit. These five cases are not allowed, so the required number is 16−1−4=11. Option A counts only pairs and omits selections of three and four fruits. Option B omits one category, while option D counts all subsets, including the forbidden selections of zero or one fruit.
