Question

Alicia rolls two fair number cubes numbered from 1 to 6. She first defines the sample space, as shown below:

(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6)
(2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6)
(3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6)
(4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6)
(5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6)
(6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)

Based on the sample space, what is the probability of getting a total of 7?

4 over 36
5 over 36
6 over 36
8 over 36

Answer 1

Answer 2

Alright so out of ALL those combinations (how many are there)

How many add to make 7?

And then your probability would be

\[\large P = \frac{\text{rolling a 7 total}}{\text{total possible outcomes}}\]

Answer 3

im pretty sure there are 6 ways to get it and there is 36 combos so it has to be c

Answer 4

^Correct :)

(1,6)
(2,5)
(3,4)
(4,3)
(5,2)
(6,1)

so

\[\large P = \frac{6}{36}\]

Answer 5

thanks both of u ^-^

Answer 7

to both of u lol
