Hey Developer’s, I’m back with a new topic which is Independence Of Events in the series of statistics foundations.

So, let’s get started …

### Independence & Dependence Events

If events do not influence one another, they are called independent.

Example:

• Successive die rolls or coin flips
• Owning a dog and growing your own herb garden.
• Paying off your mortgage early and owning a Chevy Cavalier.
• Winning the lottery and running out of milk.
• Buying a lottery ticket and finding a penny on the floor (your odds of finding a penny does not depend on you buying a lottery ticket).
• Taking a cab home and finding your favourite movie on cable.
• Getting a parking ticket and playing craps at the casino.

If subsequent events influence one another, they are dependent

Example:

• Coloured balls being pulled out of a hat without replacement. The set of possible balls gets reduced as you pull them out so probability changes.
• Robbing a bank and going to jail.
• Not paying your power bill on time and having your power cut off.
• Boarding a plane first and finding a good seat.
• Parking illegally and getting a parking ticket. Parking illegally increases your odds of getting a ticket.
• Buying ten lottery tickets and winning the lottery. The more tickets you buy, the greater your odds of winning.
• Driving a car and getting in a traffic accident.
