Which one of the following may be the parameter of a binomial distribution?

Options

  1. Anp=2,npq=4n p=2, n p q=4
  2. Bn=4,p=32n=4, p=\frac{3}{2}
  3. Cn=8,p=1n=8, p=1
  4. Dnp=10,npq=8n p=10, n p q=8

Correct answer

D. np=10,npq=8n p=10, n p q=8

Step-by-step solution

In Binomial distribution, mean (μ)>(\mu) > Variance (σ)2(\sigma)^2 i.e., np>npqn p > n p q and 0≤p≤10 \leq p \leq 1 Hence, correct option is (D).
