Sum of 15 probability with two dice

Step-by-step explanation:

all the outcomes you can get from rolling a dice twice are

2,3,4,5,6,7,8,9,10,11,12

15 is nowhere in those numbers so the probability of getting a sum of 15 is 0

answer: there are x+184 pages in olivia's book.

step-by-step explanation:
