Simplifyiing 
the greatest common factor is 3  so 
3x - 9y + 12 = 3(x - 3y + 4)
        
             
        
        
        
Answer:

<h3>What is Probability ?</h3>
Probability is the likeliness of an event to happen , 
It has a range from 0 to 1 , where 0 indicates uncertainty while 1 indicates certainty
The data for the college students is given and it has been asked to determine P(0)
The total students are 200
and the students that have no credit card from the data is 122
Therefore 
P(0) = 122/200 = 0.61
Therefore the probability that number of credit cards is 0 is 0.61
