Find the probability of rolling at least one multiple of 3 on 4 rolls of a die of 6.

OpenStudy (dumbcow):

multiples of 3 are 3 and 6, so you have a 2/6 chance probability of not rolling a multiple of 3 in 4 rolls is: (2/3)^4 Thus, probability of rolling at least 1 multiple of 3 is: 1 - (2/3)^4 = 0.802
