Even numbers between 1 and 13 are 2,4,6,8,10,12 (there are six of them) P(even number) = 6/13

P = 6/13

6/13 is the *probability*. Please don't use *odds* as a synonym. (The *odds* would be 6 to 7 in favor.) http://mathforum.org/library/drmath/view...

p(selecting even) = p(selecting 2, 4, 6, 8, 10, or 12) = 6/13

That would be 6 out of 13, which is less than half. The actual number is 6/13 = 46.2%

There are 6 evens and 7 odds. Probability of an even = 6/13

so there are 6 even numbered balls and 7 odd numbered balls. 6 even numbered balls out of 13 total balls 6/13 is the odds - or 46% if you need the precentage
