We have to divide 9/10 by 3/12. 
if we divide by a fraction, we can instead multiply by it's inverse:

so now we count:

so we can cut exactly 3 pieces!
 
        
        
        
That would be B, C and E.
A and D could be a rhombus.
 
        
                    
             
        
        
        
Answer:
0.00176
Step-by-step explanation:
Probability = 10/30 × 9/29 × 8/28 × 7/27 × 6/26
 = 56/31668
 
        
             
        
        
        
9(3+5) is equivalent because factoring a 9 out of both 27 and 45 leaves us with 9(3+5).
        
                    
             
        
        
        
Answer:
Probability that the person preferred milk as his or her primary drink  = 0.3
Step-by-step explanation:
Given - 
In a recent survey, 18 people preferred milk, 29 people preferred coffee, and 13 people preferred juice as their primary drink for breakfast . 
Total no of people is =  18 + 29 + 13 = 60
If a person is selected at random , 
 The probability of person preferred milk = 
 The probability of person preferred coffee = 
The probability of person preferred juice = 
Probability that the person preferred milk as his or her primary drink =
P ( milk ) = 
     =    =  0.3
  =  0.3
