SOLUTION: A card is drawn from a standard deck. What is the probability that a 10 or a red card is drawn? Write out
the equation in set notation and then solve it.
It can be any one of the 26 red cards or one of the two black 10s.
So it can be any one of 28 cards.
That's 28 out of 52 or 28/52 which reduces to 7/13.
