Explanation:
First of all, the total number of tiles is 25.
For part A, all you need to do is make a fraction, like this:
# of blue tiles
# of total tiles
Now, make your fraction.
=
![(1)/(5)](https://img.qammunity.org/2021/formulas/mathematics/high-school/nve42zwxkm2ttkh80stksgu37lazt1jlhm.png)
So, the probability is 5/25 or 1/5.
For part B, they are asking for both green and red. So, add the number of both green and red together, and put them as a fraction like this:
# of green and blue tiles
# of total tiles
Make your fraction.
![(3+7)/(25) = (10)/(25) = (2)/(5)](https://img.qammunity.org/2021/formulas/mathematics/college/6yxhu3qkgmpzcg9ejvjxn097hyjpknpy4a.png)
So, the probability is 10/15 or 2/5.
For part C, they are asking for all the colors except blue. So, add all colors (red, green, yellow) together, and put them as a fraction like this:
# of red, green, yellow tiles
# of total tiles
Make your fraction.
![(7+10+3)/(25) = (20)/(25) = (4)/(5)](https://img.qammunity.org/2021/formulas/mathematics/college/ql8vwktj6cyhwjklcgnsk8gu465blq40mq.png)
So, the probability is 20/25 or 4/5.
Hope this helps!
