what is the probability that a randomly chosen point on the grid below is in the blue area

So, the grid is 5 by 4 which means the shaded blue part is 12/20, since 5×4=20.
Now you have to simplify:
[tex] \frac{12}{20} \div \frac{4}{4} = \frac{3}{5} [/tex]
Answer: 3/5
Step-by-step explanation:
There are 20 total boxes, and 12 of them are blue. This means that you have a 12/20 chance of choosing blue. You can reduce 12/20 to 3/5, since 4 goes into both.
