Probability is the chance that a specific event will happen. Measuring probability helps us understand everything from health risks to weather reports to baseball.

Here’s an example:

The referee at a basketball game tosses a coin to decide which team starts. Your team picks “heads.” You've got a 1 out of 2 chance of winning the toss, since the coin can land 1 of 2 ways (either heads or tails).

When a woman becomes pregnant, there’s an equal chance that the baby will be a boy or a girl. Carol has two boys and one girl. She's pregnant with her fourth child. What is the probability that it will be a girl?
