8 12.Sophie will play a game in which she will flip a fair coin twice, then draw a card from a pile. There are 3 cards in the pile. Each card has one of the following numbers---1, 2, or 3 (all three cards are different). Assume all possible outcomes are equally likely. (Note: in flipping a coin there are two outcomes because there are two sides of a cointhese two are commonly called Heads and Tails.)a)Write out the sample space for this game. (For example one outcome is HT2heads, then tails, then a 2.) (4 points) S = {HH1, HH2, HH3, HT1, HT2, HT3, TH1, TH2, TH3, TT1, TT2, TT3} FOR parts b)through e)--Define the following events: ?: at least one Tail
b)Find 𝑃(?) (2 points)
c)Find𝑃(?𝐶)(2 points)
4
d)Find 𝑃(?|?)(3 points)
e)Find 𝑃((?𝐶∩ ?)𝐶).(3 points) can use DeMorgen’s to simplify𝑃((?𝐶∩ ?)𝐶) = 𝑃(? ∪?𝐶) = 1112or ? ∪?
f)Sophie wins the game if she gets tails twice or a 3 on her turn. What is the probability that Sophie wins? (3 points)
