Probability of rolling a sum of 9 or a sum that is even from two number cubes is
11/18
Explanation:
When a dice is rolled there are different ways in which
9. can be obtained, which are (3,6) or (4,5) or (5,4) or (6,3). 4 options. As in all there are
6⋅6=36 options, probability is 4/36 or 1/9.
For getting an even number as sum, we can have (1,1) or (1.3) or (1,5) or (2,2) or (2,4) or (2,6) or (3,1) or (3,3) or (3,5) or (4,2) or (4,4) or (4,6) or (5,1) or (5,3) or (5,5) or (6,2) or (6,4) or (6,6) 18 options, probability is 18/36 or 1/2.
Note that the two events (getting 9 or even sum) are mutually exclusive, the probabilities can be just added i.e. combined probability is
1/9+1/2=2+9/18i.e. 11/18

Some examples of additions with integers with 5 terms or more are:
- 20 + 1 + 1 + 2 + 1= 25
- 2 + 1 + 1 + 2 + 1= 7
- 20 + 2 + 1 + 2 + 1= 26
- 20 + 1 + 1 + 3 + 1= 26
- 20 + 1 + 1 + 4 + 1= 27
- 200 + 1 + 1 + 2 + 1= 205
<h3>What is an Integer?</h3>
In mathematics, an integer is a whole number that is used to represent a value and is not a fraction.
Furthermore, we can make the addition of integers as they would increment based on the number they are being incremented with and this has been shown above.
