Question

Pls help me with this

A bag contains 10 marbles: 2 are green, 5 are red, and 3 are blue. Amanda chooses a marble at random, and without putting it back, chooses another one at random. What is the probability that the first marble is red and the second is blue? Write your answer as a fraction in simplest form.

Answer 1

5/10 and 3/9

Explanation:

OK so the probability that the first one is red is simple, 10 marbles is out of 10 so, 5/10. now there are 9 marbles, then she picks another so the probability lessens to out of 9, so its 3/9
