Answer:
y=4
Step-by-step explanation:
first you that the number outside of the parenthesis and multiply it by the numbers inside 3x3y (ignore the y for right now) and 6x3 now we have          9y-18=18 now we move the 18 so the y is by itself now we have 9y=36 divide both by 9 and you get your answer y=4
 
        
             
        
        
        
The possible digits are: 
5, 6, 7, 8 and 
9. Let's mark the case when the locker code begins with a prime number as 
A and the case when <span>the locker code is an odd number as 
B. We have 
5 different digits in total, 
2 of which are prime (
5 and 
7).
First propability:
</span>

<span>
By knowing that digits don't repeat we can say that code is an odd number in case it ends with 
5, 7 or 
9 (three of five digits).
Second probability:
</span>
