Juan wants to make a new game board that is a grid containing 25 equally sized squares. How many squares should be shaded to create a region with a geometric probability of 0.2? Explain.
Answer
Answer:
The number of squares that are shaded, divided by 25, must equal 0.2, so the number of squares must be 0.2(25), which equals 5. The decimal 0.2 is equal to 2/10, so 2 of every 10 squares must be shaded.
