Given:

Total number of cards = 52

Number of cards drawn = 1

Then:

Number of ways of drawing a card from 52 cards


\begin{gathered} =^(52)C_1 \\ =52 \end{gathered}

Number of queens in a deck of cards = 4

Number of ways that one card is a queen


\begin{gathered} =^4C_1 \\ =4 \end{gathered}

Probability of drawing a queen


\begin{gathered} =\frac{\text{ Number of favorable cases}}{\text{ Total number of cases}} \\ =(4)/(52) \\ =(1)/(13) \end{gathered}

Final answer: 1/13
