Bernoulli trials and binomial distribution

Bernoulli Trial And Binomial Distribution

For a binomial distribution,

The binomial distribution has:

If the sum of the mean and the variance of a binomial distribution of 5 trials is 1.8, then find the probability of 3 successes.

The mean and the variance of a binomial distribution are 4 and 2 respectively.Then the probability of 3 successes is

The mean and the variance of a binomial distribution are 4 and 2 respectively.then, the probabitly of 2 , successes is

The mean and the variance of a binomial distribution are 4 and 2 respectively. Then, the probability of 2 successes is

Bernoulli distribution is a particular case of binomial distribution if n = ...........

If the sum of mean and variance of a binomial distribution is 4.8 for 5 trials. Find the distribution.

IF the mean and S.D. of binomial distribution are 20 and 4 respectively. Than the number of trials , is
