• Event and finding probability of

an Event

• Playing Card Video

Let us assume a situation we are watching an India v/s Australia match. And 1 ball is remaining and 5 runs are required to win.

So what do we wish should happen ?

Either India should hit a six and win the match

OR

India should hit a four and draw the match

Something that you wish should happen / should not happen

For example:

All possible Outcomes are – {Win , Lose ,Draw}

Events are denoted by Capital Letters

Let A be the event that INDIA wins

A = { Win }

Let B be the event that INDIA does not lose

B = {Win , Draw}

Any of these 3 could happen
