Customers are used to evaluate preliminary product designs. in the past, 95% of highly successful products received good reviews, 60%of moderately successful products received good reviews, and 10% of poor products received good reviews. in addition, 40% of products have been highly successful, 35% have been moderately successful, and 25% have been poor products. if a product does not attain a good review, what is the probability that it is a poor product?

step-by-step explanation:

what was your answer?

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
