Question

I forget absolutely everything having to do with probablility. So, two questions:
If two number cubes are rolled, what is the probability that both numbers rolled are even.
Annnnnnnndddddddd:
If two number cubes are rolled, what is the probability of the sum of the numbers being 5.

(6 sided dice, if that wasn't obvious.)

Answer 1

using 2 dice, how many outcomes are possible?

Answer 2

36, I would think.

Answer 3

36 is right; and i usually like to set up a chart for this:


1 2 3 4 5 6
1
2
3
4
5
6

put an "x" in all the combos that sum to 5 and count off the xs

Answer 4

1 2 3 4 5 6
1 x
2 x
3 x
4 x
5
6

i see 4 out of 36 possible ways

Answer 5

well, that should help. Thanks.

Answer 6

I can figure out the other one.

Answer 7

none of these are combos of even numbers so the answer is 0 out of 36 possibilites for a sum to be 5 AND have 2 even parts
