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
