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
