A standard deck of 52 playing cards contains 26 red cards (13 hearts and 13 diamonds). To find the probability of randomly selecting a red card, you can use the formula for probability:
\[
\text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}
\]
In this case, the number of favorable outcomes (red cards) is 26, and the total number of outcomes (total cards) is 52. Therefore, the probability is:
\[
\text{Probability} = \frac{26}{52} = \frac{1}{2}
\]
Thus, the probability of selecting a red card from a standard deck is \(\frac{1}{2}\) or 50%.
\[
\text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}
\]
In this case, the number of favorable outcomes (red cards) is 26, and the total number of outcomes (total cards) is 52. Therefore, the probability is:
\[
\text{Probability} = \frac{26}{52} = \frac{1}{2}
\]
Thus, the probability of selecting a red card from a standard deck is \(\frac{1}{2}\) or 50%.
