mean = 19/6
variance = 19*5/6/6 standard deviation = sqrt (variance) sd = 1.62 |
Re: A DIE IS ROLLED 19 TIMES $10 TO CORRECT ANSWER

sd = sqrt(npq) where n=19 p=1/6 q=5/6 |
Re: A DIE IS ROLLED 19 TIMES $10 TO CORRECT ANSWER
this is a binomial distribution so sd = sqrt(np(1-p))
p = 1/6 n = 19 sd = 1.624 e: the answer above is incorrect and tells you the variance and not the sd e2: big biceps edited it to my answer |
