Two standard number cubes are thrown simultaneously. What is the probability that the combined result of the two standard number cubes is exactly 7, or that it is greater than (but not equal to) 10?
A 0.007
B 0.014
C 0.25
D 0.83

Answer 1

Not a 100% positive but I believe that your answer would be C.

Answer 2

Answer with Step-by-step explanation:

P(Event)=no. of favorable outcomes/total no. of outcomes

Sample Space on throwing two standard number cubes is:

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

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

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

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

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

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

Total outcomes=36

Outcomes with combined result of the two standard number cubes is exactly 7, or that it is greater than (but not equal to) 10=9

Hence, P(combined result of the two standard number cubes is exactly 7, or that it is greater than (but not equal to) 10)=9/36

= 1/4

= 0.25

Hence, correct option is:

C 0.25
