In a city it is found that 10 accidents took place in a span of 50 days. Assuming that the number of accidents follow the Poisson distribution, the probability that there will be 3 or more accidents in a day in that city is

  1. A \(1-(1.02) \mathrm{e}^{0.2}\)
  2. B \(1-(1.22) \mathrm{e}^{-0.2}\)
  3. C \(1-(1.2) \mathrm{e}^{0.2}\)
  4. D \(1-\frac{1.22}{\mathrm{e}^{-0.2}}\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(1-(1.2) \mathrm{e}^{0.2}\)

Step-by-step Solution

Detailed explanation

\(X \sim\) poisson \((\lambda)\) \(\operatorname{Mean}(\lambda)=\frac{10}{50}=\frac{1}{5}\) \(P(X \geq 3)=1-P(X=0)-P(X=1)-P(X=2)\)…
