Answer:
Part A) [tex]\frac{5}{25} or \frac{1}{5}[/tex]
Part B) [tex]\frac{10}{25} or \frac{2}{5}[/tex]
Part C) [tex]\frac{20}{25} or \frac{4}{5}[/tex]
Step-by-step 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.
[tex]\frac{5}{25}[/tex] = [tex]\frac{1}{5}[/tex]
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.
[tex]\frac{3+7}{25} = \frac{10}{25} = \frac{2}{5}[/tex]
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.
[tex]\frac{7+10+3}{25} = \frac{20}{25} = \frac{4}{5}[/tex]
So, the probability is 20/25 or 4/5.
Hope this helps!
