Two balls are drawn in succession out of a box containing 2 red and 4 white balls. Find the probability that at least 1 ball was red, given that the first ball was
(A)Replaced before the second draw.
B)Not replaced before the second draw
ok so we know that there is 2 red and 4 whit so for every 1 red ball you get 2 white therefore the ratio is 1red/2white. But im really not understanding this question then again i just stared my adhd meds today for the first time in 2 weeks
