Answer: C .08
Explanation:
Probability is the part out of the whole. you first need to find the part, which is the triangle
In other words find out how much of the triangle is taking up the rectangle, which is done through area
A(triangle)=1/2 b h where b=6 h=9
A(triangle)=1/2 (6)(9) = 27
A(rectangle)= Lw where L=24 h=15
A(rectangle)= (24)(15) = 360
P(triangle in rectangle)= 27/360
=.075 rounded = .08
