If for a binomial distribution with `n=5, 4P(X=1)=P(X=2)`, the probability of success is

In a binomial distribution with n= 4 2. P(X=3) =3. P (X=2) ,then the vlaue of p is

For a binomial variable X if n=5 and P(X=1)=8P(X=3), then p=

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

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

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.

If for a binomial distribution P(X=1)=P(X=2)=alpha, write P(X=4) in terms of alpha.

If X follows Binomial distribution with parameters n=5, p and P(X=2)=9P(X=3), then p is equal to ……. .

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

The mean and variance of a binomial distribution are 30 and 5, respectively. Then probability of two successes is
