3. A hat contains 3 coins - 1 gold, 1 nickel and 1 bronze. You will select coins one at a time with no replacement until you choose the gold coin. The outcome of interest is the sequence of coins that are selected during this process.

What is the appropriate sample space? I have a hard time figuring this out.

bump... help please ;_;

n= nickel
b=bronze
g=gold

{nbg, bng, ng, bg, g}

i further need an explanation about this... sorry

Those are the five possible sequences of coins.

S= {nbg, bng, ng, bg, g}

so gnb, gn, gb are not appropriate because g is in the first "coin" ???

reread the problem:


You see, every solution must end with you choosing the gold coin.

ah got it thanks!
