A) profit/original price x100 =percentage profit
(Profit: 360-300=$60)
=60/300 x100
=20%
b) two cameras (original price): 300x2= $600
 two cameras (price sold): 360x2 = $720 
Profit without discount: 720-600= $120
120-100= $20 discount
20/720 x100 =2.78%
        
                    
             
        
        
        
Answer: Odds in favor = Number of successes: Number of failures
Step-by-step explanation: 
Example

Number of successes = 5
Number of failures = 2 + 6 = 8
Numbers of ways to draw a white pearl: number of ways to draw another jewelry.
