A fair die is cast 8 times. Calculate the probability of obtaining exactly four 6's.

You can solve this by applying the binomial probability formula that I gave you in response to your other post - see: https://www.askmehelpdesk.com/mathematics/mathematics-618837.html

For this problem the probability of succcess for one throw of the die yielding a 4 is p=1/6. Post back with your answer and we'll check it for you.
