What is the probability that a point chosen at random in the triangle is also in the blue square?
O 1/6
O 1/3
O 1/2
O 1

Area of a triangle = 1/2 x base x height.
Area of the shown triangle = 1/2 x 9 x 6 = 27 square inches.
Area of blue square = 3 x 3 = 9 square inches.
The probability of being in the blue are of the triangle = 9/27 which reduces to 1/3
