Maths homework-probability?
Emily Asked: Maths homework-probability?
A bag contains 2 black beads, 5 yellow beads and 3 red beads. Natalie takes a bead at random from the bag, records its colour and replaces it. She does this two more times.
Work out the probability that, of the three beads Natalie takes, exactly two are the same colour.
Thank you!
