Revolt · Accepted Answer

0.785

Question 9

Revolt · Accepted Answer

0.215

Question 10

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.

Revolt · Accepted 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.
