Explanation / Answer

As per the Chegg policy, we are advised to do one question at a time so i am attempting 23rd.

23. Option A is incorrect as the trails should be independent in binomial situation.

B is incorrect because normal distribution never crosses or touches the x - axis.

C is incorrect as there is a differecnce.

For Poisson, mean and variance are same so Option D is incorrect.

Hence,

Option E is correct.
