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

Answer:
x= -6
Step-by-step explanation:
Notice that a(-6,7) and b(-6,-3) have the same x-coordinate (-6). This means that x is constant and that the line is a vertical one (x = -6).
The equation of the line through these two points is x = -6.
It appears that the digit 9 is prepended to each term of the sequence 5^(n-1).
The next two terms will be 5^5 and 5^6, each with 9 prepended: 93125 and 915625.
