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
