<PRE><B>Question 210399</B>
 A lottery game has balls numbered 1 through 15. What are the odds of selecting an even numbered ball or a 8?
----
P(even or 8) = P(even) + P(8)- P(even and 8) 
= 7/15 + 1/15 - 1/15 = 7/15
---------------------------------------------

============================================= 
I need help because I am confused how both answers can be the same. numbers 1-15 have 7 even numbers in between meaning this probabilty would be 7:15 but getting an 8 out of 1-15, wouldnt that be 1:8? the choices are between-
A) 

15 : -7 

B) 

7 : 8 

C) 

7 : 15 

D) 

8 : 7
