A card is drawn from a pack of 52 cards. The probability that the card drawn is a red card is

The deck is split evenly between red and black cards.

So we have 52/2 = 26 red cards

P(Red) = # of Red Cards / Total Deck Cards
P(Red) = 26/52

We can simplify this fraction. Using our fraction calculator, we get:
P(Red) = 1/2 or 0.5
