Question 3 (14) Suppose that you repeatedly play a game where you roll a fair six-sided die. You win $10 if the number of dots faces up is 6. Otherwise, you win $1. Let $S_n$ be the total amount that you win after $n$ games and assume that you don't have any money in the beginning. (a) (2) Find $E[S_{10}]$ (b) (2) Find $VAR[S_{10}]$. (c) (2) Find $COV(S_{10}, S_{20})$. For the following questions (c) to (g), only give a clear mathematical expression and no need to provide a numerical answer. (d) (2) Find the probability that you win $28 in 10 games, $P[S_{10} = 28]$. (e) (2) Find $P[S_{30} = 120|S_{10} = 28]$. (f) (2) Find $P[S_{30} = 120 \cap S_{10} = 28]$. (g) (2) Assume that you now start out with $10 and each time you play the game costs you $4. The cost of playing the game is paid after completing 10 times. What is the probability that you have money larger than $5 after playing the game 10 times?

Ethane (C_(2)H_(6)) reacts with oxygen according to the following chemical equation: 2C_(2)H_(6)+7O_(2)->4CO_(2)+6H_(2)O a) If you mix 5 moles of C_(2)H_(6) with 13 moles of O_(2), how many moles of each substance will you end up with, assuming the reaction goes to completion? Include an ICE table in your answer. b) If you mix 81.43g of C_(2)H_(6) with 194.60g of O_(2), how many grams of each substance will you end up with, assuming the reaction goes to completion? Include an ICE table in your answer. (Note: your ICE table should be in terms of moles.) c) A chemist mixes 3.414 moles of O_(2) with an unknown amount of C_(2)H_(6).
