Answer 2

Okay, so your first thing to do is find out how many different outcomes you can get from rolling two dice. How many sides are on one dice?

Answer 3

one die*

Answer 4

does it count if you do 3+1 and 1+3

Answer 5

i think it is 1/4

Answer 6

Yes, it does count if you do 3+1 and 1+3

Answer 7

so that would come to 3/12

Answer 8

Answer 9

No...

Answer 10

Let's go back to the first step. How many total outcomes can there be?

Answer 11

i got 3

Answer 12

1+3,3+1,2+2

Answer 13

do you count 2+2 again or no

Answer 14

Yes.

Answer 15

so then 4/12 then what is the next step

Answer 16

Okay, so you found the number of outcomes result in a sum of 4. That's good, because we're going to need that later.
But what is the TOTAL number of outcomes that can come from rolling two dice?

Answer 17

No, not 4\12

Answer 18

There are 4 outcomes that will result in a sum of 4, but there are a lot more than 12 total outcomes

Answer 19

You have two dice, each with six sides. That means 6 x 6 total combinations (outcomes). What is 6 x 6?

Answer 20

i don't think i am right but do you do 6*6

Answer 21

okay i do got it right 4 /36 then simply

Answer 22

so the answer is 1/9
