In a binomial distribution, $\displaystyle \mathrm{n}=200$ and $\displaystyle \mathrm{p}=0.04$. Taking Poisson distribution as an approximation to the binomial distribution :
Assertion (A): Mean of Poisson distribution = 8.
Reason (R): $\displaystyle \mathrm{P}(\mathrm{X}=4)=\frac{512}{3 \mathrm{e}^8}$.
Official answer
(B)
Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
