Binomial Distribution Mock Tests

If X follows a binomial distribution B(n, p) with n = 6 and p = 1/2, the mean is:

A binomial random variable X has mean 4 and variance 3. The probability that X = 2 is:

In a binomial distribution, the mean is 4 and the variance is 3. The number of trials n is:

The variance of a random variable X with P(X = 0) = 1/2, P(X = 1) = 1/2 is:

A coin is tossed 4 times. The probability of getting exactly 2 heads is

In a binomial distribution, the mean is 4 and the variance is 3. The probability of getting exactly 2 successes is:

A coin is tossed 5 times. What is the probability of getting exactly 3 heads?

A binomial distribution has mean 6 and variance 4. Then P(X = 0) is:
