Answer: no lol
Step-by-step explanation:
Answer:
626.7 
Step-by-step explanation:
Consider the figure as a circle with radius 7.5 and a rectangle with width 30 and length 15.
CIRCLE
A = pi*r*r = pi*7.5*7.5 = 56.25pi =176.7
RECTANGLE
A = l*w = 15*30 = 450
176.7 + 450 = 626.7 
The probability will be :
C(12,2) / C(40,2) = 11/130, which is around 8.46%
