Answer:
$3.02
Step-by-step explanation:
Jenna bought 3 pairs of socks that costed her $2.00 each.
So, $2.00 times the 3 pairs she bought is $6.00.
Jenna also bought a blouse for $5.98
$6.00 from the 3 pairs of socks she bought and $5.98 from the blouse would equal a total of $11.98
Jenna gave the cashier $15.00
$15.00 minus the total of $11.98 is $3.02
Jenna recieved $3.02 back
 
        
             
        
        
        
Step-by-step explanation:
we can factor out z
so that'll be
z((1/m)-(1/n))=1
divide by the value in parentheses on both sides
z=1/((1/m)-(1/n))
I can't tell if there's more the problem wants you to do. I could rewrite the equation on paper more easily, but I don't have one on hand
 
        
                    
             
        
        
        
The sample space will be: {1, 2, 3, 4, 5, 6}
Event A is: {Rolling 1,2 or 3}
Complement of event A will contain all those outcomes in the sample space which are not a part of event A.
So, complement of event A will be: {Rolling a 4,5 or 6}
Thus option A gives the correct answer
