Question

PLEASE HELP!!!

Henry has a bag of marbles. The bag contains 4 red marbles, 2 blue
marbles, 3 green marbles, and 1 yellow marbles. She will randomly select two marbles from
the bag one at a time without replacement What is the probability that Henry will select a
blue marble first and then a yellow marble?

Answer 1

i havnt done this topic in maths for agesss but i can try and help. so overall there are 4 + 2 + 3 + 1, which is 10. so the probability that she will pick out a blue marble first is 4/10 i THINK. and the probability that she’ll pick out a yellow marble is 1/10.
