Question

Two dice, one blue and one grey, are thrown at the same time. Write
down all the possible outcomes. What is the probability that the sum
of the two numbers appearing on the top of the dice is 0) 8 (0) 13
(iii) Less than or equal to 12
​

Answer 1

Step-by-step explanation:

possible outcomes=(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)

I) sum equal to 8= (2,6) (3,5) (4,4) (5,3) (6,2)

I.e, there are 5 cases

probability=5/36

2) sum equal to 13= there is no such cases

probability=0/36=0

3) sum less than or equal to 12 =all cases

probability=36/36=1
