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

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:

1. Find the total area of the triangle:

2. Find the desired area of the square:

Then the probability is

correct choice is B
