Question

Tina has a bag of marbles. The bag contains 6 red marbles, 3 blue marbles, and 1 yellow marble. She will randomly select 2 marbles from the bag one at a time without replacement. What is the probability Tina will select a blue marble and then a red marble?

Answer 1

you add the amount of marbles together first (6+3+1) which is 10, so your answer is going to be ?/10. for blue it’ll be 3/10 because there are 3 blue marbles out of 10 marbles in total. and for red it’ll be 6/10.
