What is the probability of not rolling any 6’s in four rolls of a balanced die?
a) Consider the complement problem, there is a 5/6 probability of not rolling a six for any given die, and since the four dice are independent, the probability of not rolling a six is (5/6)4 = 54/64 = 625/1296.
What is the probability of rolling a 6 four times in a row?
You have to calculate the odds of not rolling a 6 and then subtract the result from 1.0. Therefore, the odds of rolling a 6 within four rolls is 1 – 0.482 = 0.5177; 0.5177 x 100 = 51.77% are your odds of rolling a 6 in 4 tries, 52% if they are asking you to round the number.
