Step-by-step explanation:
impossible. chance or probabilty is 0.
to pick 2 values (an ace AND a 3) with the pick of one card is simply impossible.
now, if you mean to pick an ace OR a 3, the desired events are one of the 4 aces in the deck, or one of the four 3s (with the 4 suits in the deck : clubs, diamonds, hearts and spades).
so, from a typical deck of 52 cards (I assume there are no jokers) we desire one of 8 of these cards in our pick.
and as a probability is always the ratio
desired cases / totally possible cases
we have here a probability
8/52 = 2/13 = 0.153846154...
