a) 7/12
b) 1/6
Step-by-step explanation:
(1)
Number greater than 5 include;
6, 7, 8, 9,10, 11, & 12
= 7
Prbabilyt of event = number of outcome / total number of possible events
= 7/ 12
(2)
Total number of possible events = 180 * 12
= 2160
Number of outcomes for;
Rolling a 3 = 1 * 120 / 2160 = 120/2160
Rolling a 9 = 1 * 120/2160 = 120/2160
Rolling a 11 = 1 * 120/2160 = 120/2160
Since we are using the OR rule, well add the possibilities
120/2160 * 3
360/2160
= 1/6
