Answer:
7/9
Step-by-step explanation:
P(blue) = 2:7 
This means there are 2 blue parts for every 7 nonblue parts. So 9 parts total! 2:7, then, should be thought of as 2/9.
P(not blue) = 1 - 2/9
                   = 7/9
Think about it: there must be a total probability of 1, so the probability of <em>not</em> getting blue must be 7/9.
 
        
             
        
        
        
It says to estimate first 1,537 turns to 2,000 because the 5 is 5 or more so the 1 becomes 2 and everything else is zeros. Now multiply 2000x 242=484,000 is the Estimation. Now find the correct product for 1,537x242=371,954
