5/6

Step-by-step explanation:

2/4 the first time you pick then 1/3 the second time

then after you take a even card out the total becomes 3 so you then count again how many even cards are left and you put that over 3 so the second part of the answer would be 1/3

the you add the 2 probabilitys together to get 5/6 as the answer
