math-independent and dependent events
posted by Jocelyn on .
A card is chosen at a ramdom from a deck of 52 cards.It is then replaced and a second card is chosen.What is the probability of getting a jack and then an eight?
getting a jack 4/52. Then getting an eight 4/52
Probability of getting a jack and then an eight, given those are the two cards picked is 1/2 ( the other way of getting them is in reverse order)
Joint probablity: 1/2 * 4/52 * 4/52
What does it mean when an event is dependent or independent? I have a question i don't understand.
Event A: A class President is chosen
Event B: A school president is chosen from a list of class presidents.
You are supposed to say whether the events are dependent or independent. Please Help!
RESPOND PLEASE! THIS IS HOMEWORK I HAVE TO HAVE DONE TONIGHT!
well look at it this way, when the outcome of the first event affects the outcome of the second event, the events are dependent events.
