In a book consisting of 600 pages, there are 60 typographical errors. The probability that a randomly chosen page will contain at most two errors, is
- A \(\frac{1}{5} \sqrt{e}\)
- B \(\frac{1}{e^{0.1}}\left(\frac{221}{200}\right)\)
- C \(\frac{1}{e^{0.1}}\left(\frac{111}{200}\right)\)
- D \(\frac{1}{5} e^{0.1}\)
Answer & Solution
Correct Answer
(B) \(\frac{1}{e^{0.1}}\left(\frac{221}{200}\right)\)
Step-by-step Solution
Detailed explanation
\(\begin{aligned} & \text { (b) We have, } \lambda=\frac{60}{600}=0.1 \\ & \therefore \quad P(X=x)=\frac{e^{-\lambda}(\lambda)^x}{x !}=\frac{e^{-0.1}(0.1)^x}{x !}\end{aligned}\)…
