If we toss one coin twice, what would be the Sample Space? This paper says that: S = {HH, HT, TH, T T}.
I don't think its correct. I think it is the result of tossing two coins in one experiment.
To my thinking, S = {H,H,T,T}, or, may be, S = {{H,T},{H,T}}.
Is that right?
Can you also talk about the Example-7 on the paper?

tossing one coin twice is the same as tossing two coins once (the sample space I mean). when you toss one coin twice these are the possibilities. (first flip gives H,second flip gives H),(first flip gives H,second flip gives T),(first flip gives T,second flip gives H) and (first flip gives T,second flip gives T).Hence, the sample space is (H,H),(H,T),(T,H),(T,T)
