A container has 3 apple juice boxes, 4 grape juice boxes and 5 orange juice boxes. Alex picks one juice box, drinks it and then picks another juice box. What is the probability that Alex picks grape juice and then orange juice?

Hey!

Grape over total:
(4)/(12)

After he drinks 1, there will be 1 less. That means it will be over 11

Orange over total:
(5)/(11)

Now multiply the fractions


(4)/(12) * (5)/(11) = (20)/(132) \rightarrow (10)/(66) \rightarrow (5)/(33)

That means the probability is:
(5)/(33)

Good luck and hope this helps! :)
