The area of rectangle A is 5(7) = 35 in². The area of rectangle B is 3(4) = 12 in² The area of square C is 4(4) = 16 in² The area of rectangle D is 3(9) = 27 in²
The total area of the figure is 35+12+16+27 = 90 in².
The probability of hitting B is 12/90 which simplifies to 2/15.
Well, it depends if its positive or negative. 2 positive integers will equal a positive, 2 negatives will equal a negative. A negative and a positive will depend.
