Determine the probability P (3) for a binomial experiment with n = 12 trials and the success probability p=0.2. Then find the

mean, variance, and standard deviation.

Part 1 of 3

Determine the probability P (3). Round the answer to at least three decimal places.

P (3) = 0

Part 2 of 3

Find the mean. If necessary, round the answer to two decimal places.

The mean is

Part 3 of 3

Find the variance and standard deviation. If necessary, round the vanance to two decimal places and standard deviation to

at least three decimal places.

The variance is

The standard deviation is
