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.

Let the number of shaded square be x. And it is given that total number of squares are 25.

Substituting the values

Performing cross multiplication

So 5 squares should be shaded to create a region with a geometric probability of 0.2 .

3x + 4y -25 =0 represents the amount of change sianna should recieve

6mm^3 or .6cm^3

6     6   6

factor trees are nice.
