<p>At North High School, the ski club has 15 members and the debate club has 12 members. If a total of 11 students belong to only one of the two clubs, how many students belong to both clubs?</p>

<p>The answer is 8.</p>

<p>I got the right answer but I'm not sure if I did it correctly.
I did 15-11, 12-11, and 15-12 to get 4, 1, and 3 respectively, and then added them together to get 8..</p>

<p>Is my process correct?</p>

<p>no, it’s not correct. there are a total of 27 members, 11 of which only belong to one club. Thus, the other 16 slots are filled by members in 2 clubs. so there are 8 people (in 2 clubs)</p>
