Question

A bag contains 10 marbles: 6 are green, 2 are red, and 2 are blue. Frank chooses a marble at random, and without putting it back, chooses another one at random. What is the probability that the first marble is green and the second is red? Write your answer as a fraction in simplest form.

Answer 1

You have to do a tree diagram I can't show u but all I can tell u is u have to add all the marbles together to make 20 and the first part to the question is 6/20 but u have to take away 2/20 overall the answer could be 3/20 averaging it but this is estimated so u have to draw a tree diagram to make sure it's correct

Answer 2

for the green it would be 6/10 and the red 2/10
