a bag contains 2 red beads, 1 yellow bead and 3 green beads. A bead is chosen at random.
(2 red beads, 1 yellow bead, and 3 green beads)
What is the probability that is not yellow?
Add all the beads together: 2 red + 1 yellow + 3 green = 6 beads in total Add together all the beads that are NOT yellow: 2 red + 3 green = 5 beads Put the 5 that are not yellow over the total number: 5/6 is the probability that the bead selected at random will NOT be yellow
