Homework Statement An Urn contains two white marbles and one black marble. A marble is drawn from the Urn without replacement and put aside without my seeing it. Then a second marble is drawn, and it is white. What is the probability that the unknown removed marble is white, and what is the...

Yes thank you. This was a big part of what was confusing me. The .5 prob of picking either with replacement or without.

Thank you for your responses. The first problem I struggled with was understanding P(getting this combination|no replacement) = 1. After some thought and discussion I figured this out because nothing will be left in the container. Next I was having trouble with getting some of the values for...

Homework Statement An urn contains 50 marbles – 40 blue and 10 white. After 50 draws, exactly 40 blue and 10 white are observed. You are not told whether the draw was done “with replacement” or “without replacement.” What is the probability that the draw was done with replacement? Homework...

Yes thank you. That helped. Appreciate your guidance.

Sorry about the bold font. I did not realize that was offensive or I was even doing it. Thank you for pointing it out. I also appreciate your guidance on this question. I tried the binomial theorem for exactly 8 heads and that has led me to one of the choices. So that is what they must be...

Homework Statement Suppose I have a bent coin with a 60% probability of coming up heads. I throw the coin ten times and it comes up heads 8 times. What is the value of the “likelihood” term in Bayes’ Theorem -- the conditional probability of the data given the parameter. Homework...

Thank you for your response, but I am not very comfortable with these concepts yet. P(A|B) = probability of event a occurring given that B has taken place right? Then what is P(A,B)? Sorry I have not yet studied Bayes rule. Is there a good tutorial you could recommend? Thank you.

Thank you. Yes just did that and it is much easier. Not sure how I can post a tree here on this forum. Would love to know if you use any tools to do that sort of thing regularly.

Thank you so much. This was really helpful. Could you please also let me know how to built that table in this thread? Is there a tool here that helps with that? Since I don't know how to make that table yet I'll just write it out. (E,F) = 0.1 (~E,F) = 0.2 (E,~F) = 0.05 (~E,~F) = 0.65 The...

Homework Statement I am given the following 3 joint probabilities: p(I am leaving work early, there is a football game that I want to watch this afternoon) = .1 p(I am leaving work early, there is not a football game that I want to watch this afternoon) = .05 p(I am not leaving work early...
