Answer: 1/10

Step-by-step explanation:

1: Let’s take out the “DO NOT REPLACE IT.” It can make the whole thing seem harder. Rather, here is this. “There are five marbles in a bag, 3/5 are green and 2/5 are yellow. You DRAW TWO MARBLES. What is the chance of you drawing two yellow marbles?”

2 : Now let’s look at some important information.

100% of marbles= 5 marbles.

60% of marbles= the three green marbles.

40% of marbles= the two yellow ones.

Picking 2 of the 5 marbles will mean taking 40% of the marbles out of the bag.

Simplify: Now, to make it easier, the question is this. what is the chances of the 40% being the same color, Specifically yellow.

3: Let me explain. There are two yellow marbles, you pick out two. That is a one out of five chance of you getting ONE yellow marble the first time. That is 1/5. picking two at the same time results in a 2/5 chance.

4: if you pick twice it would be 1/10 chance.
