The sum and the product of the mean and variance of a binomial distribution are 24 and 128 respectively. Find the distribution.

Explanation

Solution

Correct option is A)

Let the binomial distribution be `({p}+{q})^{{n}}`

We have,

Mean =n p

Variance =n p q

Given n p+n p q=`24`

`n p(1+q)=24`
