Answer:
by moving the decimal in both numbers twice to the right and doing normal long division (the decimal in 3 is at the end) to get the answer of 0.72
 
        
                    
             
        
        
        
P(picking one defective) = 3/10
P(picking a 2nd defective) = 2/9
P(1 and 2  defective) = 3/10 x 2/9  = 6/90 = 0.066
Second method using combination:
 ³C₂ / ¹⁰C₂ = 1/15 = 0.066
