independent and dependent events

Question

Which events are independent?

 

(a) you draw two colored cards at the same time and get one red and one green

(b) you choose two different ice cream flavors

(c) you draw a card from a deck, replace it and draw a second

(d) you draw a card and don't replace it.  Then you draw another.

Answer 1

Independent events do not affect each other. You flip a coin, you flip it again. What you got on the first does not influence what you get on the second.

 

Dependent events do affect each other. You pick a red ball out of a bag and put it aside. That act changes the chances of picking another red ball.

 

Now with this, which one do you pick?
