Question

Finding theoretical probability throwing a dart in a 3x3 yellow square that is centered inside a 6x6 blue square

Answer 1

The probability of hitting the yellow square is 1/4.

The area of the yellow square is given by 3*3 = 9.
The area of the blue square is given by 6*6 = 36.

You have a 9/36 chance of hitting the yellow square; 9/36=1/4.
