Teaching Transcript

🎙️

What is the probability of flipping heads on one coin?

Probability is just the number of outcomes we want, which we call desired outcomes, divided by the total number of possible outcomes

There's only one outcome we want, because there's only one way to flip heads

There are two possible outcomes, head or tails

So our probabilty is 1 over 2, or 0.5, or 50%
