Question

how many students do not ski or ice skate?

Explanation:

Step1: Add up all the numbers in the Venn diagram

$$7 + 2+13 + 4+3+6+10=45$$

Step2: Assume the total number of students is \(45 + 6\) (the number outside the Venn diagram which represents students who don't ski or ice - skate)

The total number of students in the context of the Venn diagram (including the non - skiers/non - ice - skaters) is calculated by summing all the values. The number of students who do not ski or ice skate is the value outside the Venn circles.

Answer:

16 (assuming the number outside the Venn diagram in the left - most box (green) is the answer for students who do not ski or ice skate. If the Venn diagram is in a universal set where the number outside the three - circle Venn (for ice - skating, skiing, snowboarding) is the value for students who don't do either of the first two, and from the given options, if we consider the standard Venn diagram interpretation where the number outside the relevant circles (ice - skating and skiing) is the answer. Here, if we assume the left - most number (16) is the one representing students who do not ski or ice skate)
