Given a standard deck of 52 cards, we must find the probability of randomly drawing a red card. We know that:
• # of red cards = 26,
,• # of cards in the deck = 52.
The probability of drawing a red card is given by:
[tex]P(\text{red card)}=\frac{\#\text{of red cards}}{\#\text{of cards in the deck}}=\frac{26}{52}=0.5.[/tex]Answer
The probability of randomly drawing a red card is 0.5 or 50%.
