### Introduction to probability

In this section, we practice finding the probability of events. Probability is the likelihood or chance of an event occurring. We will practice expressing probabilities as ratios, fractions, decimals, and percents. Probability can be calculated using the following equation: $Probability=\frac{Favourable\ outcomes}{ Possible\ outcomes}$. P(blue) is a short way to write "the probability of blue".
