Question:1

You are playing a game where a fair die is rolled fifirst and then a fair coin is tossed a number of

times equal to the face of the die (e.g. if the die shows three, the coin is tossed three times, and this

combination is considered as one game).

a)[1 point] Let X be the number of heads(H) you can get in any game.

Write down the probability mass function of X. (this part is not a simulation question. Calculate

ALL the probabilities and produce a table that represents the pmf)

Calculate E[X] using your pmf.

b)[1 point] Write an R code that will simulate this game 100,000 times.

save the outputs from your simulation(no need to print the outputs).

Use these outputs to calculate an estimate of E[X].

c)[1 point] Suppose you are told that if the number on the die is odd you get a dollar value equivalent

to the corresponding X value(e.g. the die shows three, the coin is tossed three times, if there are two

heads you get $2).

But if the number on the die is even, you have to pay a dollar value equivalent to X.

Calculate an estimate of your expected gain from each game (You can use numeric calculations

as you have done in part(a) or you can use your simulation from part(b) to answer this question).

Expected output:

(a) Numeric calculations and a pmf table.

(b) R code and just one line of R output giving your estimate.

(c) Either show numeric calculations or R code with one line of output depending on how you

answered it.
