Answer:

a) 7/12

b) 1/6

Step-by-step explanation:

(1)

Number greater than 5 include;

6, 7, 8, 9,10, 11, & 12

= 7

Probability 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

120/2160 * 3

360/2160

= 1/6
