looks good, the mean is lambda and the standard deviation is the square root of lambda
If a random variable X follows Poisson distribution such that
P(X=1)=P(X=2)
Compute
i) the mean of distibution
ii) P(X=0)
iii) standard deviation of the distribution
Solution
Poisson distribution
since
.................Am i correct ??????
