Answer:
12*6*3=216
Step-by-step explanation:
First multiply !2 and 6 to get 72 .Then multiply 72 and 3 to get 216.
 
        
             
        
        
        
Answer:
C, The marble is 3 times as likely to be black as it is to be white. 
Step-by-step explanation:
The probability of a marble being drawn is:
number of marbles of that color/total number of marbles
Find total number of marbles
5+8+4+15= 35
So the probability of drawing:
white: 5/32
polka dot: 8/32
striped: 4/32
black: 15/32
The probability of drawing white, polka dot, or striped is obviously different, so A is wrong. 
The probability of drawing every color but black is 5/32 + 8/32 + 4/32 = 17/32, which is more than the chance of drawing black, so B is wrong. 
The probability of drawing black is 15/32, and that is 3 times larger than the probability of drawing white (5/32), so C is correct. 
The probablility of drawing a polka dot is 8/32, which is not four times as large as stripe (4/32), so D is wrong.

 The order to us solve is:
- Parentheses
- Multiplication
- Sum and subtraction
Let's go:

Therefore, the result is 62.2.
