Sample 200 bolts

24 bolts ae defective for poor workmanship

34 bolts are defective due to size too big

158 bolts meet specification

if a bolt is selected what is s the probability that it wilill be defective for 1 too large. large

2.poor workmanship but not b0th

Am I on the right track

P = 24 +34/200

P(24/34) = P(24 * 154)/200

I am quite sure how to approach this problem
