Question

You roll 2 die. What is the probability that the sum of the dice is greater than 8 and that 1 die shows a 6?
I'm a bit confused with this problem because the second clause (at least one die must show a 6) interferes with the first - ie In order to have more than 8 as a total, you must leave out '4' and '4' for the second part.
Can anyone help?

Answer 1

lets count

Answer 2

(6,3),(6,4),(6,5),(6,6),(3,6),(4,6),(5,6) am i missing any?

Answer 3

I think that's correct, to fulfill the requirements?

Answer 4

Ohhh. Psh, I'm silly. Thank you.

Answer 5

ok then the number of favorable ones above, divided by the total which is 36

Answer 6

Answer 7

If I had a more complicated problem with more die than I could count, is there some sort of formula/method I could use?

Answer 8

i like counting

Answer 9

with dice it is easiest
you can verify that whatever formula you use is correct with dice however

Answer 10
