A dice is rolled 4 times. What is the probability of showing a 2 on every roll?

Answer 1

For roll #1: the probability of getting a 2 (aka P(2)) is 1/6

For roll #2: P(2) = 1/6

For roll #3: P(2) = 1/6

For roll #4: P(2) = 1/6

The probability that it happens each time is (1/6)•(1/6)•(1/6)•(1/6) = 1/1296
