Question

If you roll two number cubes, what is the probability of their sum being seven or higher?

Answer 1

Yea

Answer 2

Right

Answer 3

ok so if u roll a dice u will get two numbers

Answer 4

Yea

Answer 5

Equal to

Answer 6

or higher

Answer 7

even 5+6 = 11
and 6+6 = 12

Answer 8

Yeah,

Answer 9

What?

Answer 10

easiest method is to count

Answer 11

That'd give you the probability?

Answer 12

fill in a dice table, let me see if i can find one
count how many, then divide by 36

Answer 13

here i feel it would be 22

Answer 14

22/36?

Answer 15

The answers to choose from are 5/7, 5/12, 7/5, and 7/12

Answer 16

Which would reduce to 5/12

Answer 17

i am still looking for a table, but the idea is to count how many of each
there are
6 ways to get a 7
5 ways to get an 8
4 ways to get a 9
3 ways to get a 10
2 want to get an 11
1 way to get a 12

for a total of \(6+5+4+3+2+1=21\) ways to get a number 7 or higher

Answer 18

so your answer is \(\frac{21}{36}\) which you can reduce

Answer 19

So the answer would be 7/12,
Thank You!!

Answer 20

still can't find one, but it should look like this

1 2 3 4 5 6

1 2 3 4 5 6 7
2 3 4 5 6 7 8
3 4 5 6 7 8 9
4 5 6 7 8 9 10
5 6 7 8 9 10 11
6 7 8 9 10 11 12

Answer 21

now everything is a matter of counting how many times you see the sum in the table

Answer 22

i have to remember dices
at least they didn't call them "number cubes"
