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= 4Ă—5 sq. in.
= 20 sq. in.
The area of blue triangle=

= 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
