Question

In a bundle of 50 shirts, 44 are good, 4 have minor defects and 2 have major defects. What is the probability that it is acceptable to a trader who accepts only a good shirt? 

Answer 1

Total number of shirts = 50 

Total number of elementary events = 50 = n(S) 

Since trader accepts only good shirts and number of good shirts = 44

Event of accepting good shirts = 44 = n(E) 

Probability of accepting a good shirts = `(n(E))/(n(S)) = 44/50 = 22/25`
