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?

1/5

Step-by-step explanation:

there is only one yellow bead 2 red and 3 green you add the red and green with a total of 5 getting a ratio of 1/5

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
