What we have here is an overlapping Venn diagram question. You know, you have two circles that represent two populations, and then some overlapping section.

Check out my reply to: https://www.beatthegmat.com/ds-overlappi ... html#46089. This details the strategy for this type of question, and provides a solution for a similar question.

If you are still stumped after reading that, please let me know and I can detail this question for you.

Best wishes,

Tatiana
