The probability that a 2 or a 3 card is dealt from a pack of 52 cards is $\frac{2}{13}$.
We know that the total number of cards of 2 in a deck is 4 and the total number of card of 3 in a deck is 4. Therefore, the total number of favorable outcomes is $=4+4=8$ And the probability that a 2 or a 3 card is dealt is given below, \begin{align} & P\left( \text{dealt a 2 or a 3} \right)=\frac{\text{number of 2 and 3 cards}}{\text{total number of cards in the deck}} \\ & =\frac{8}{52} \\ & =\frac{2}{13} \end{align} Hence, the probability that a 2 or a 3 card is dealt is $\frac{2}{13}$.
