Q38 of 53 Page 15

A carton consists of 100 shirts of which 88 are good, 8 have minor defects, and 4 have major defects. Jimmy, a trader, will only accept the shirts which are good, but Sujatha, another trader, will only reject the shirts which have major defects. One shirt is drawn at random from the carton. What is the probability that

(i) it is acceptable to Jimmy?


(ii) it is acceptable to Sujatha?

Total number of bulbs = 100


Total number of good bulbs = 88


Bulbs having minor defects = 8


Bulbs having major defects = 4


(i) it is acceptable to jimmy only it is good


P(it is acceptable to Jimmy) =


(ii) She will accept all the bulbs which do not have major defects. So, total bulbs acceptable to her is 96


P(it is acceptable to Sujatha) =
