Question

(probability) Getting a sum of either 5 or 9 on a roll of two dice

Answer 1

Answer:

2/9

Step-by-step explanation:

From the image, the total number of outcomes when two die are rolled = 36

It can also be seen that a sum of 5 can be got 4 times and a sum of 9 can be got 4 times too

Therefore, the probability of getting a sum of 5 = 4/36

Probability of getting a sum of 9 = 4/36

The probability of getting either a sum of 5 or 9 gives;

4/36 + 4/36

= 2/9
