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

probability = \frac{shaded \ squares}{total \ squares}

Substituting the values

0.2 = \frac{x}{25}

Performing cross multiplication

0.2*25=x \\ x = 5

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