I could use some help on this. I've tried many different formulations of the problem (basic AND/OR probability calculations, binomial distribution, etc) and I always get the answer 0.903 for part B, and I can't understand why that isn't the answer. I've also done other potentially correct things and gotten different results (like 0.980 when doing certain formats of AND/OR logic on the probabilities), so I'd like some insight because I'm not getting any closer personally, just trying random things at this point.
