Solution

A standard deck of cards has 4 suits: Hearts, Clubs, Spades, and Diamonds

Each suite contains an ace, 2, 3, 4,5,6,7,8,9,10, jack, queen, and king, a total of 13 cards

Therefore a standard pack of cards has 4 x13 cards = 52 cards/elements

An expression for probability is


P(A)\text{ = }\frac{No\text{ of required events}}{No\text{ of total possible events}}

The question requires us to find the probability of picking an Ace or a Club

No of Aces = 4 across all the suits

No of Clubs = 4 across all suits

Total number of cards = 52


\begin{gathered} \text{Probability of Aces = }(4)/(52) \\ \text{Probability of Clubs =}(4)/(52) \end{gathered}

The probability of picking an Ace or a Club is


(4)/(52)+(4)/(52)=(8)/(52)=(2)/(13)

Answer = 2/13
