**PsyDAG**, Thursday, June 9, 2011 at 10:45amAt least one red = one, two or three reds = 4/12 * 3/11 * 2/10 = P (three reds)

4/12 * 3/11 * 8/10 = P (two reds)

4/12 * 8/11 * 7/10 = P (one red)

Either-or probability is found by adding the individual probabilities.

The above data can be used to answer all three questions.
