Probability of picking a shape from a bag

This skill teaches how to calculate the probability of picking a specific shape from a bag. The probability is determined by dividing the number of desired outcomes (e.g., picking a red triangle) by the number of all possible outcomes (e.g., all shapes in the bag).

What is the probability of picking a red triangle from the bag?

🎙️

Probability is always the count of the outcomes we're looking for, divided by the count of all possible outcomes.

🎙️

We have 2 different ways to pick a red triangle

🎙️

And 5 possible ways to pick a shape from the bag

🎙️

So our probability is 2 out of 5. That's the same as 0.4, or 40%
