1/16
1/15
15/17
15/16

Answer 1

Answer:

Step-by-step explanation:

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

1/2

Step-by-step 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=

                                        = 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
