Answer:
1/4
Step-by-step explanation:
This is an event of 1/4 cards
If events became two different numbered cards with no replacement it would become 1/4 x 1/3 = 1/12
With replacement the odds get larger as there are more cards if picking two specified as random. 1/4 x 1/4 = 1/16
if it was the same number and not replaced it becomes 0/12 as 1/4 x 0/3 = 0/12 = 0
