The volume of a cereal box is 400 mm³. The height of bx is 20mm.

To calculate for the standard deviation given the probability, we use the formula:

s = sqrt (n p q)

where s is standard deviation, n is number of samples = 11, p is probability of success = 0.7, q = 1 – p = 0.30

s = sqrt (11 * 0.7 * 0.3)
