Answer :

Total numbers of elementary events are: 100

The number of good shirts = 88.

The number of shirts with minor defects = 8.

Number of shirts with major defects = 100 – 88 – 8 = 4.

(i) Let E be the event of shirt getting accepting by Rohit

The numbers of favourable outcomes = 88

∴ P (the drawn shirt is acceptable to Rohit) = P (E) = 88/ 100 = 22/25

(ii) Let E be the event of shirts getting accepted by kamal

The number of favourable outcomes = 88 + 8 = 96

∴ P (the drawn shirt is acceptable to Kamal) = P (E) = 96/100 = 24/25
