Document Summary
Let"s think about how we think about being dependent and independent in our everyday lives: A person who is dependent (like a child), needs another person to survive. They would be dependent on an adult for cooking them meals and giving them a place to live. A person who is independent, doesn"t need anyone else but themselves to survive. They can make their own food, pay the bills to their home, etc. In a similar sense, events in probability can be dependent or independent. Let"s see if we can look at pairs of events and see if they are dependent or independent! Ask yourselves, do one of the events affect the other? : event a: going to mcdonalds every monday, wednesday and friday before class. Event b: suddenly gaining a lot of weight. : since event a impacts event b, it is dependent: event a: swiping right to every single person on tinder.
