First you will have too find the least common multiple which is 20 and what you multiplied to get 20 multiply it which will make 3/5 to 12/20 and 1/4 too 4/20 and then subtract the two which is 8/20 or 8 oranges. if you need more information talk too me
        
                    
             
        
        
        
If you would like to know how many feet of fencing does Laurel need in all, you can calculate this using the following steps:
square garden: 4 * 50 feet = 200 feet
3 square rose beds: 3 * 10.5 feet * 4 = 12 * 10.5 feet = 126 feet
200 feet + 126 feet = 326 feet
Laurel will need 326 feet of fencing.

If the probability of independent event A is 0.5, then P(A|B) will be 0.5. Then the correct option is B.
<h3>Which pair of events are called independent events?</h3>
When one event's occurrence or non-occurrence doesn't affect occurrence or non-occurrence of other event, then such events are called independent events.
Symbolically, we have:
Two events A and B are said to be independent iff we have:
 P(A ∩ B) = P(A)P(B)
Comparing it with chain rule will give 
P(A|B) = P(A)
P(B|A) = P(B)
Suppose A and B are dependent events.
If P(A) = 0.5 
Then P(A|B) will be 
P(A|B) = P(A)
P(A|B) = 0.5
Then the correct option is B.
