# Basic Probability Examples

### Example 1

If you draw a card from a standard deck of cards, what is the probability of drawing a face card? | There are 4 suits with 3 face cards each. This makes a total of 3 × 4 = 12 face cards out of 52 cards. |

If you draw a card from a standard deck of cards, what is the probability of | There are 13 spades, so that means that there are 52 – 13 = 39 cards that are not spades. |

### Example 3

If you roll two dice, what is the probability that the sum of the two is odd? | As we can see in the chart above, there are 18 combinations that result in an odd sum. There are still 36 different combinations, so: |
