Question

binomial distribution is symmetrical when

Answer 1

Answer:

The mean of a binomial distribution is p and its standard deviation is sqr(p(1-p)/n). The shape of a binomial distribution is symmetrical when p=0.5 or when n is large.

Step-by-step explanation:

The parameter 'p' in Binomial Distribution decides whether the distribution is symmetric or not. If p = 1/2, then the distribution is symmetric.

Answer 2

binomial distribution is symmetrical when they are zeros of the polynomial.
