To find the number of ways to choose 3 types of fruit from 7, you can use the combination formula, which is denoted as ( C(n, r) = \frac{n!}{r!(n-r)!} ). Here, ( n = 7 ) and ( r = 3 ). Thus, the calculation is ( C(7, 3) = \frac{7!}{3!(7-3)!} = \frac{7 \times 6 \times 5}{3 \times 2 \times 1} = 35 ). Therefore, there are 35 ways to choose 3 types of fruit from 7.
