dale placed six cARDS IN A BAG.QONE CARD IS LABELD 1,TWO CARDS ARE LABELD2,AND RTHREE CARDS ARE LABELD 3.FIND THE PROBABILITY OOF PICKING TWO CARDS IN THE ORDER OF THE NUBERS LISTED TH EFIRST CARD IS RETURNED BEFORE THE SECOND IS PICKED ..... P,(1,2)

Question

P(3,NOT1)
p(NOT2,2)
P(1,3)
P(2,3)
P(2,NOT2)

I will do one for you, I am pretty sure you can do the rest.

P(3,not1):

to get a 3, Prob. = 3/6 or 1/2
to get "not 1", there are 5 of "not 1), so the prob. of "not 1" = 5/6

since you are returning the cards, each event is independent of the next,
so
the P(3,not 1) = 1/2 * 5/6 = 5/12
