A fair number cube labeld 1,2,3,4,5,6 is rolled a hundred times. about how many times could you expect to roll a three?

So probability is (desired outcomes) / (total possitlble outcomes)

desired is 1 since 3 appaears once on the cube

6 total possible

so probaity of rolling a3 is 1/6

100 times

100 times 1/6=100/6=16 and 2/3 times

round up

17 times
