Question

you roll two dice.what is the probability that the sum of the dice is even or the sum of the dice is greater than 6 ? Make sure you only account for dice sums that are both even and greater than 6 once

Answer 1

It's much better to look at the opposite event namely even and less than 6, coz and is always easier than or.

Probability to get 2 = 1/36 , 4 = 3/36, 6 = 5/36, total 9/36 = 1/4.

So answer 1 - 1/4 = 3/4.

Answer 2

the answer is 5/6
