प्रश्न
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 rejects only a shirt with major defects?
उत्तर
Total number of shirts = 50
Total number of elementary events = 50 = n(S)
Since trader rejects shirts with major defect only and number of shirts with major defect = 2
Event of accepting shirts = 50 – 2 = 48 = n(E)
Probability of accepting shirts = `(n(E))/(n(S)) = 48/50 = 24/25`
