the answer is 2/6 because you have to add all of them together and if you are taking two out then that is the mumerator, lol but tbh when you take one ball out first i think that there would either be a 1/5 or 2/5 chance depending on if you get a white ball or not.

Hey there! :) 

2 red , 3 white , 1 blue = a total of 6 marbles

If 2 marbles are drawn from the bag, then that's 2 marbles out of six. 

So, our probability is 2/6. However, because there are 3 white marbles, this gives us a higher probability that 2 of those six marbles pulled are white. 

So, our final probability is 3/6 , or 1/2 simplified.

~Hope I helped!~
