8. A carton consists of 100 shirts of which 88 are good. 8 have minor defects and 4

have major defects. Johny a trader only accepts that shirts which are good. But

Sujatha another trader will only rejects which have major defects. One shirt is

a) It is acceptable to Johny

b) It is acceptable to Sujatha

c) Acceptable to both of them

d) Not acceptable to both of them​

Answer 1

Total number of shirts = 100

Number of good shirts = 88

Number of minor defected shirts = 8

Number of major defected shirts = 4

(1) Acceptable shirts to johny = 88

Therefore required probability 88 = 0.88

100

(2) Acceptable shirts to sujata = 88+8= 96

Therefore required probability = 96 = 0.96

100
