Question 1071556
So then look at the possible choices,
Even:{2,4,6,8,10}
Odd : {1,3,5,7,9}
Face:{J,Q,K}
There are {{{5*4=20}}} possible odds, {{{5*4=20}}} possible evens, and {{{3*4=12}}} possible face cards. 
So the probability of an even card is the number of even cards divided by the number of total cards,
Even : {{{P(E)=20/52=5/13}}}
Odd : {{{P(O)=20/52=5/13}}}
Face : {{{P(F)=12/52=3/13}}}
