Basically, probability is a simple fraction: The total number of ways that something could happen in the denominator and the number of ways that are considered a success in the numerator. Sometimes it gets a little tricky to count the ways something could happen, but fortunately these three problems are pretty straightforward

For all three of these problems, the denominator is the same. There are 52 cards in the deck, so there are 52 different things that could happen when you draw one card.

There are 3 face cards in each of 4 suits, so there are 12 cards any one of which would be considered a successful outcome if you wanted to draw a face card. Hence, the probability is:

There are 4 of any given number 2 through 10, so the probability of drawing a 4 is:

There are no cards numbered 15, so the probability of drawing a 15 of either color, much less a red one is:
