Face masks are supplied to a junior college in packets of If there is a chance that in face mask is defective, then the number of packets containing no defective face masks in a consignment of packets, is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
The probability of getting a defective mask is p=1500 and the number of masks in a packet is 100. Using Poisson's distribution, we know that in a large sample, the probability of an event X to occur r times is PX=r=e-λλrr!, where λ=np. Here, we have…
