### Richard's BOB on PROB

One thing I can say about probability is that you need to understand the situation to get the right solution...

we follow some basic rules such as if it is "and" it means that we multiply probabilities and if it says "or", we add probabilities. But we also need to know if it is mutually exlcusive or not, independent or dependent...

...but there's only one thing that we shoulld always keep in mind regarding the probabilities, it is a number between **0** and **1** and the sum of the probabilities of the events will always equal to **1**...

I hope everyone will do good on the test..Good luck and God Bless!!
