Efficacy of .52 means we should expect some cures.

I’m a bit confused about the numbers. Is .52 the probability of success or failure? I hope I remember this correctly!

I feel like I might have seen a similar question where we calculated the probability of success and failure.

I think we need to find the probability of none being cured first, then subtract from 1. That sounds familiar from practice problems.

I remember we talked about the binomial formula in class, but I'm not sure how to apply it here.
