There are 30 students in math class. Twelve belong to the photography club. Three belong to both clubs. How many belong to neither club?
Is it 12?
need more information... are any involved in just the other club?
is this question missing some information? What is the other club and how many people are in that one?
To determine the number of students who belong to neither club, we need to subtract the number of students who belong to at least one club from the total number of students in the math class.
Given that there are 30 students in the math class, and 12 students belong to the photography club, we can calculate the number of students who belong to at least one club by adding the number of students in the photography club with the number of students in the math club (since the three students who belong to both clubs would be counted twice):
12 (photography club) + X (math club) - 3 (students in both clubs) = number of students who belong to at least one club
To find the number of students who belong to neither club, we subtract this result from the total number of students:
30 (total students) - (12 + X - 3) = number of students who belong to neither club
Simplifying the equation:
30 - 12 - X + 3 = number of students who belong to neither club
18 - X = number of students who belong to neither club
Since we do not know the value of X, we cannot determine the exact number of students who belong to neither club based on the given information alone.
