Question 1042963
1,2,3,4,5,6,7,8,9,10,11,12,13


There are 6 even numbers in that list above (2,4,6,8,10,12). Since selecting a 4 is a subset of the event of selecting an even number, we just need to worry about the even numbers. 


There are 6 ways to select a ball we want out of 13 ways total. Therefore, the probability as a fraction is 6/13. The probability as a decimal is 0.461538 (use a calculator to compute 6/13 = 0.461538). This decimal value is approximate.
