Question

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

A) 1/6  (it's not A i cheeked)
B) 1/3
C) 1/2
D) 1

Answer 1

Yes the person above me was correct the is B 1/3

Explanation:

Answer 2

The probability that a point chosen at random in the triangle is also in the blue square can be calculated using geometrical definition of the probability:

`Pr=\frac{\text{desired area}}{\text{total area}}.`

1. Find the total area of the triangle:

`A_(total)=(1)/(2)\cdot 6\cdot 9=27\ in^2.`

2. Find the desired area of the square:

`A_(desired)=3\cdot 3=9\ in^2.`

Then the probability is

`Pr=(9)/(27)=(1)/(3).`

Answer: correct choice is B
