Question 259308: Suppose there are two green packages and five white packages in a sack. If two packages will be selected without replacement, what is the probability that the first package is white and the second package is green?

2 green, 5 white, 7 total
P(first package white)=5/7
2 green, 4 white, 6 total
P(second package green)=2/6
Together, since the event are independent the probabilities multiply.
P=(5/7)(2/6)=5/21
