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.

When the outcome of one event does not affect the outcome of another event, the events are considered independent events. In the given scenario:
Event A: A class President is chosen
Event B: A school president is chosen from a list of class presidents
In this case, the events are dependent because the outcome of Event A (choosing a class President) affects the pool of candidates for Event B (choosing a school president). The class president must first be chosen before they can be considered for the position of school president. Therefore, the events are dependent.
