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

Answer:The probability that a point chosen at random in the rectangle is also in the blue triangle is:1/2Step-by-step explanation:We are given a figureWe 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=[tex]\dfrac{1}{2}\times 4\times 5[/tex]                                          = 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
