The probability that the sum of both rolls is at least 9 is 2/36.
Probability is the chance that a given event will occur. the ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.
Given:
Total sample spaces: 36.
Number on one dice: 6
For sum of both rolls to be 9 , the only possible way is (6,3)(3,6)
Using probability formula,
Thus The probability that the sum of both rolls is at least 9 is 2/36.

Answer:
1/3
Step-by-step explanation:
Slope is rise over run
your rise is 1 (because you only go up one block each time)
your run is 3 ( because you go right three times)
so 1/3
Answer:
8x + 2y - 23
Step-by-step explanation:
(2y + 5) + (5x - 17) + (3x - 11)
2y + 8x + 5 - 17 -11
2y + 8x - 23
Answer:
17
Step-by-step explanation:
The expression of interest is the difference of the two given expressions.
(-4x +6y) -(-2x -7y) = (9) -(-8)
-2x +13y = 17
The value is 17.

<em>Additional comment</em>
You could go to the trouble to solve the two equations for x and y, then compute the value of the expression you want. As we saw above, that is not necessary.
The first step in problem solving is always "look at the given information and how it relates to what you are asked." A little time spent doing that can save a lot of effort in the actual problem solving process.
It should be noted that the expression that.can be used to describe the sequence below is an = 2 + (n - 1)
<h3>How to illustrate the information?</h3>
It should be noted that an arithmetic sequence implies that the difference between the pair are the same.
It should be noted that the common difference between the numbers is illustrated as:
= 3 - 2 = 1.
Therefore, it should be noted that the expression that can be used to describe the sequence below is an = 2 + (n - 1)
