What is the probability of getting a sum 9 from two throws of a dice?

1/9

Step-by-step explanation:

Probability is:

# of desired outcomes/# of total outcomes

First, we can find the number of total outcomes.

6*6=36

They are as follows:

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

This is where (here is the value of the first dice role, here is the value of the second dice roll)

Now, I am going to bold all the outcomes that add up to 9.

Notice that there are 4.

So there are 4 desired outcomes and 36 total outcomes.

4/36

Simplify

1/9

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
