A.0.202
B.0.075
C.0.101
D.0.083

Answer 1

Assuming the die is a standard 6-sided die, the probability of getting a 2 four times in a row is the same as rolling for any other number: 1/6. Since you want to find the probability of getting exactly four twos, simply multiply 1/6 four times (or (1/6)^4). This will get you roughly 0.075.
