The binomial distribution has

For Bernoulli distribution with probability p of success and q of a failure, the relation between mean and variance is -

The mean and probability of success of a binomial distribution are 4 and 0.4 respectively. What is the variance?

In an experiment, positive and negative values are equally likely to occur. The probability of obtaining at most one negative value in five trials is

If for a binomial distribution n = 5 and 3P(X = 2) = P(X = 3), the probability of success is

Suppose a unbiased die is thrown 72 times and getting a 4 on a throw is termed as success then find the variance of number of success ?
