well, it's not a right angle (90 degrees), it's not a 45 degree angle, and it's not a straight angle (180 degrees), so it's not enough info
  
        
                    
             
        
        
        
Answer:
Probability that a customer pays the bill by mail, given that the customer is female is 0.20.
Step-by-step explanation:
The complete question is: 
                                Online                             By Mail            Total 
              Male             12                                      8                   20
            Female           24                                     6                   30       
              Total             36                                     14                  50     
A utility company asked 50 of its customers whether they pay their bills online or by mail. What is the probability that a customer pays the bill by mail, given that the customer is female.
Probability that a customer pays the bill by mail, given that the customer is female is given by = P(Pays bill by mail / Customer is female)
 P(Pays bill by mail/Customer is female) =
P(Pays bill by mail/Customer is female) = 
Now, Probability that customer is female =  
Also, Probability that customer pays bill by mail and is female =   
So, Required probability =  
                                          =  
                                          =   =  0.20
   =  0.20
Hence, probability that a customer pays the bill by mail, given that the customer is female is 0.20.
 
        
             
        
        
        
You divide 1 by 4.76 and you get 0.21 as your main answer

Answer:
f(n+1) = 13
Step-by-step explanation:
- We know that f(1) = 15
- So we can substitute this for f(n)-3
- With this:
- f(n+1) = f(1) -3 
- f(n+1) = 15-2
- f(n+1) = 13
