A fair coin is tossed. If a heads occurs, 1 die is rolled. Let Y be the total on the die or dice. What is the expected value of Y?

Question

venomblast · Answer

The probability of Heads and Tails is 1/2. We need to figure out for Y right?

OK, so do we have to count those instances when a tail occurs as Y = 0?

And are we flipping the coin a set number of times?

venomblast · Answer

Im not sure

venomblast · Answer

I think Y is the sum of both cases

Is there more than one die? The question indicates more than one die... I found a similar question (and answer) but I can't quite relate it to what you are asking. question #6: http://www.utm.utoronto.ca/~w3act/act245h5f/ps5.pdf
