What is the probability to get a red card in a pack of cards?

Total number of cards in a pack = 52
Number of red cards = 26
Probability of getting a red card

 $$\begin{gathered} = \frac{\mathrm{Number} \mathrm{of} \mathrm{red} \mathrm{cards}}{\mathrm{Total} \mathrm{number} \mathrm{of} \mathrm{cards}} \\ = \frac{26}{52} \end{gathered}$$
