A fair die is rolled four times. Calculate the probability of obtaining exactly two 5s. (Round your answer to four decimal places.)
Added by Richard S.
Step 1
This can be done by multiplying the probability of rolling a 5 (1/6) by the probability of not rolling a 5 (5/6) for the other two rolls. Therefore, the probability of rolling exactly two 5s in one roll is (1/6) * (1/6) * (5/6) * (5/6) = 25/1296. Show more…

Suppose you roll a fair die repeatedly. What is the probability that you will need to roll the die 10 times until you see the first '5'? (Give 4 decimal places)
