The following chips are placed in a bucket: 5 red, 3 yellow, 4 blue, and 1 green. One chip is randomly selected from the bucket. How often will a blue chip be selected?4 out of 13
4 out of 8
1 out of 13
4 out of 9

Answers

So,

If we add them together, we get
5 + 3 + 4 + 1 = 13

Since there are 4 blue chips, the probability would be 4 out of the total number of chips, or 4/13.

The \ probability \ of \ the \ random \ selection \ of \ a \ blue \ chip \ is \ (4)/(13) .
4 out of 13 because 13-9=4 so thats what i think

-12x1/6x3+48/3 Pleaseee help me

Answers

First, let's look at the first two nomials. -12 / 6 = -2 and x / x3 = 1 / x2

Since the bigger variable is on the bottom, when simplifying it stays on the bottom.

We get -2/ x2 + 16.

48/3 = 16.

Is1/10 and 3/33 epuivalant

Answers

3/33 can be reduced to 1/11 by dividing by 3 on the top and bottom.
1/11 is not equal to 1/10. Although they have the same numerator or number on top, 1, they don't have the same number in the bottom. 
So they are not equivalent.
Hope this helps. 
No,

3/33 equals 1/11 and 1/11 is smaller than 1/10. so they are not equal.
