What are the mean and standard deviation of a binomial probability distribution with #n=12 # and #p=5/37 #? Statistics Random Variables Mean and Standard Deviation of a Probability Distribution 1 Answer Gary M. · Clupeid Nov 18, 2015 #"Mean" = 12*5/37 = 60/37 = 1.62# #"Standard deviation" = (12*5/37*32/37)^(1/2) = 1.18# Explanation: #"Mean" = "n"*"p"# #"SD" = ("n"* "p"*"q") ^(1/2)# #"q" = 1-"p"# Answer link Related questions How do you calculate the standard deviation of a bounded probability distribution function?
