fhhuber & richardkel are correct. A visual way to ‘see’ this problem/solution is to lay out coins showing all possible customer purchases. A heads = good and tails = defective. There are 4 possible purchases (1st coin is different than 2nd coin). 1 has no defects, one has two defects, and two have 1 defect.
That said, the cartoon is still funny (at least to me:) The funny (cry type) part comes when you realize that some companies think ‘buy one, get one free’ will cover for defect rates of 1% or 0.1%.
Why is it tails is always the defective one? Are you a tail bigot? What do you have against tails?Where’s the ACLU when you need to file a tail discrimination suit?
If you are trying to get at least one that is not defective, then the success rate would be 75%: 50% one of them is good; plus 25% both are good, which is better than 50/50.

I’m no mathemetician, God knows, but wouldn’t that mean of at least 50% that you’d get TWO defectives?

25% get 2 good ones, 25% get 2 bad ones, 50% get one good one.

there’s a fine line between 2 to 1 and 2 against 1.
