Question

a box contains 20 red marbles and 30 blue marbles. a second box contains 10 white marbles and 40 black marbles. if you choose one marble from each box without looking, what is the probability that you get a blue and a back marble

Answer 1

To get a blue marble from the first box, it would be a 3/5 chance (60% or .6)
To get a black marble from the second box it would be a 4/5 chance (80% or .8)
