Answer:

The probability that a point chosen at random in the rectangle is also in the blue triangle is:

1/2

Explanation:

We are given a figure

We have to find the probability that a point chosen at random in the rectangle is also in the blue triangle.

Area of rectangle= 4×5 sq. in.

= 20 sq. in.

The area of blue triangle=
(1)/(2)* 4* 5

= 10 sq. in.

P(that a point chosen at random in the rectangle is also in the blue triangle)

= area of blue triangle/whole area of the rectangle

= 10/20

= 1/2
