Question 748569: Robert will roll a number cube, labeled 1 through 6, a total of 200 times. About how many times could Robert expect to roll a number greater than 4? Answer by timvanswearingen(106) (Show Source):
You can put this solution on YOUR website! Since he has a 1/3 chance of rolling a number greater than 4 (those numbers being 5&6, thus 2/6 numbers which reduces to 1/3).
Rolling 200 times, multiply:
So about 67 times if you round up.
