A bag contains 5 blue marbles, 8 green marbles, 4 red marbles, and 3 yellow marbles.
Event A = drawing a green marble on the first draw
Event B = drawing a blue marble on the second draw
If Jasmine draws two marbles from the bag, one after the other and doesn’t replace them, what is P(B|A) expressed in simplest form?
I will start you out.
A 8/(5+8+4+3) = ?
B 5/(5+7+4+3) = ?
If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
