Probability of picking a card with even number,
P(even 1) =
= 
= 
= 
Followed by picking a card which is even without putting the first card back.
So an even card is to be picked out of remaining 3 cards.
P(even 2) = 
= 
Now probability of both events = P(even 1) × P(even 2)
= 
= 
Therefore, probability of both the events will be
.
