**PsyDAG**, Sunday, November 25, 2012 at 1:16pmAssuming that the balls are replaced, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.

a) (6/16)^3 * (10/16)^3 = ?

If they are not replaced,

a) 6/16 * 5/15 * 4/14 * 10/13 * 9/12 * 8/11 = ?

Depending on replacement or not, go through the similar processes with the remaining problems.

b) Here you are considering 4 or 5 red balls. "More" indicates that there has to be at least one white ball. (Either-or probabilities are found by adding the individual probabilities.)

c) Here you are considering 5 or 6 white balls
