Answer:

Part A)
(5)/(25) or (1)/(5)

Part B)
(10)/(25) or (2)/(5)

Part C)
(20)/(25) or (4)/(5)

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.


(5)/(25) =
(1)/(5)

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)

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)

So, the probability is 20/25 or 4/5.

Hope this helps!
