Well the two events are independent (whatever the first one is doesn't effect the outcome of the second dice)
So the P(dice one)=the number of results you want divided by the number of sides. The P(dice two)= the number of results you want divided by the number of sides. The Probability you want is just the product of the two probabilities of the dice by the definition of independent events. If you need more help than this just right me. |
