Doubt in A OR B (Mutually Exclusive)

Hello Everyone!

In the PrepSwift A OR B (Mutually Exclusive) video, I simply solved questions using total! divided by repeats! it worked in some cases, but when the following question came…it didn’t work there.

Can I follow this approach?

More context needed - what did you do before?

I’m saying that for this question, I couldn’t move ahead with the Total! / Repeats!

Where are the repeats though? I don’t get your point.
