What is probability?

*Probability* is the chance that something will happen. Its a way to measure how likely an event is, using numbers between 0 and 1.

*Think of it like this:*

– *0* = impossible. It will never happen. Example: rolling a 7 on a normal 6-sided die.

– *1* = certain. It will definitely happen. Example: the sun rising tomorrow.

– *0.5* = 50/50 chance. Could go either way. Example: flipping a coin and getting heads.

*Basic formula:*

Probability = Number of ways the event can happen / Total number of possible outcomes

*Example*: Drawing a red card from a deck.

There are 26 red cards out of 52 total.

So probability = 26/52 = 0.5, or 50%.
