+35 Hi everyone! This is my first time using this site. If I am doing anything wrong or if I should fix anything, please tell me! Thank you all very much! :D
Suppose we have a bag with 10 slips of paper in it. Eight of these have a 3 on them and the other two have a 9 on them.
a) What is the expected value of the number shown if we add one additional 9 to the bag?
b) What is the expected value of the number shown if we add two additional 9's (instead of just one) to the bag?
As I said, thank you all so much!

If you are polite and seriously interested in learning then you will like it here.
You could have chosen a more positive name though 
Thanks CalculatorUser for your answer. I like answers like this.
JAFN (just another failure not) take a look at the video and see if it helps.
Think deeply (with a pen in your hand) about what the video has tried to teach you.
Then write a response.
Always say thanks but if you do not understand then say that too.
+35 ahhh . . . sorry about the name! I suppose I can't change it now. Oops.
First, @CalculatorUser thank you for recommending a video. I will try to work the problems. Also, Melody, I have not watched the video yet (I'm at school) but after I do, I will make sure to update you both. Thank you for helping me!
I'm sorry for the username (to be fair, I was argu-talking with my parents) and I will follow both your advice.
Again, thank you :)
