Find the binomial probability distribution whose mean is 3 and variance is 2 .

Options

  1. A( 2 3 + 1 3 )^9
  2. B( 5 3 + 2 3 )^9
  3. C( 3 3 + 1 2 )^9
  4. DNone of these

Correct answer

A. ( 2 3 + 1 3 )^9

Step-by-step solution

We have, aligned & n p=3, n p q=2 q= 2 3 & p=1-q=1- 2 3 = 1 3 , n=9 aligned Hence, the binomial distribution is (q+p)^n= ( 2 3 + 1 3 )^9
