Problem
If you roll a fair six-sided die and a fair four-sided die, what is the probability that neither die shows a 1?
+37170 Hmmmmm..... I'm a little confused as to how a 'four sided' die shows ANYthing. Isn't it basically of a triangular pyramid shape?
+23254 The probability of not getting a 1 on a cube is 5/6.
The probability of not getting a 1 on a tetrahedron is 3/4.
The probability of not getting a 1 on either of them is: (5/6) · (1/4)
+37170 Still have a problem with the tetrahedron......when it is rolled it lands on one face...the other three faces are equally showing....wouldn't the probability of NOT showing a '1' then be 3/4 ?
+37170 OOppps....sorry...didn't type that correctly....

wouldn't the probability of NOT showing a '1' be just 1/4
