Answer:
11/18
5/9
Step-by-step explanation:
Make a table showing all the possible sums for two dice:
Of the 36 possible sums, 18 are even, 7 are multiples of 5, and 3 are both even and multiple of 5. So the probability is:
P(even or multiple of 5) = (18 + 7 − 3) / 36 = 22/36 = 11/18
Of the 36 possible sums, 12 are multiples of 3, 9 are multiples of 4, and 1 is a multiple of both 3 and 4. So the probability is:
P(multiple of 3 or 4) = (12 + 9 − 1) / 36 = 20/36 = 5/9
