You can put this solution on YOUR website! probability of picking a blue marble is 2/10 or 1/5, a red marble is 3/10 and a white marble 5/10 or 1/2. The last two have probability greater than 1/5. Two white marbles in succession have a probability of 1/2*4/9=2/9, which is greater than 1/5.
the green is 1/4. After that, there are three left, and the probability of choosing a red marble is 1/3. That product is 1/12, which represents the probability of green first then red.

Hello,
I have read the first line of your post, and I do not understand what are the events you are talking about.
As I see from the post, you simply DO NOT UNDERSTAND what you are writing/printing in your post.
If you do not understand IN PRINCIPLE what you write, then you better do not post to this forum, at all.
And another advise is ABSOLUTELY MANDATORY:
NEVER post more than one problem per post.
