Final answer:
The probability of being dealt a two or a black card is 7/13.
Step-by-step explanation:
To find the probability of being dealt a two or a black card, we need to determine the number of favorable outcomes and divide it by the total number of possible outcomes.
There are four two cards in a deck, and there are 26 black cards (13 spades and 13 clubs).
However, two of the two cards are already counted as black cards, so we should subtract 2 from the total black cards.
The probability is therefore (4 + 24)/ 52 = 28/52 = 7/13.
