You close your eyes and pick from a bowl of four apples: an apple is always, a banana is never, and each fruit moves onto a line from never to always. One banana is added, so both fruits become sometimes, and counting four apples and one banana shows that an apple is more likely and a banana is less likely.

Transcript

What the lesson says

How likely is it? Let's pick some fruit and see.

This bowl has four apples. One, two, three, four.

Close your eyes and pick one fruit.

Will it be an apple? Yes, every time. Always!

Will it be a banana? There are no bananas. Never!

Now let's add one banana to the bowl.

Now you might pick the banana. Sometimes!

You will not always get an apple now. Sometimes!

Let's count. One, two, three, four apples. One banana.

Four is more than one. So an apple is more likely.

Only one banana. So a banana is less likely.

Lots of apples, more likely. Just one banana, less likely.
