You can put this solution on YOUR website! Three members of your family (two parents and yourself) went to buy three cell phones. The phones come in three colors: red, blue and black. You all pick them randomly. What is the probability that all three phones will be red or blue?
----
For each individual: P(red or blue) = P(red) + P(blue) = 1/3 + 1/3 = 2/3
---
For all three indicuals: P(red or blue) = (2/3)^3 = 8/27
