Inside a rectangle with sides equal to 15 cm and 8 cm, there is a square with a side of 6 cm.

Inside a rectangle with sides equal to 15 cm and 8 cm, there is a square with a side of 6 cm. A point inside the rectangle is randomly marked, what is the probability that this point will be located outside the square?

The area of the rectangle is 15 * 8 = 120 cm ^ 2.

The area of the square inside the rectangle is 6 * 6 = 36 cm ^ 2.

The area of the figure, which is a rectangle with a square cut out of it:

120 – 36 = 84 cm ^ 2.

Then the probability that a point randomly selected in the rectangle will be located outside the square is equal to:

84/120 = 21/30 = 7/10 = 0.7.

Answer: 0.7.
