Binomial probability distribution is denoted by b(x ; n, p), is defined as _______________?
Correct answer: A. {nx}px qn-x
- A. {nx}px qn-x
- B. {nx}px(1 - P)x-n
- C. nCxpnqnx
- D. {nx}p(1 - P)x
Explanation
The binomial probability for exactly x successes is C(n,x)p^xq^(n−x), where q = 1 − p. Option (a) represents this formula; the other expressions have incorrect or incomplete powers.
