In this lesson, you will learn that probability represents the chance of something happening and has a value between 0 and 1. You will apply this knowledge to find the probability of simple events.

Essential Question: How can probabilities help us understand the likelihood that something will happen and enable us to make predictions and informed decisions?

On your nature walk, you observe the following quantities of each bug:

If your observations are representative of the whole population of bugs in the area, which bug are you most likely to see?

Asemmisa {{asɛmmisaAhyɛnsode}}
2.

How do you know?

Asemmisa {{asɛmmisaAhyɛnsode}}
3.

Given a single die, let's find the probability of rolling a 6.

Total sides on single die:

Total sides of die showing a "6":

Probability of rolling a "6":

You found a special type of die with another 6-sided die inside:

4.

The probability that the two dice sum to 6 is \frac{5}{36}.
