If the probability of a bad reaction from a vaccination is 0.01 , then the probability that exactly two out of 300 people will get bad reaction is
- A \(\frac{7}{2 e^3}\)
- B \(\frac{9}{2 e^3}\)
- C \(\frac{7}{e^3}\)
- D \(\frac{9}{e^3}\)
Answer & Solution
Correct Answer
(B) \(\frac{9}{2 e^3}\)
Step-by-step Solution
Detailed explanation
Probability of a bad reaction from a vaccination is 0.01 \(P=0.01\) and \(n=300\) Here, binomial distribution is applicable with poission approximation mean \((\mu)=n p=0.01 \times 300=3\) Apply poission distribution,…
