Question

A coin is tossed . Write the Sample Space (S) .
​

Answer 1

The sample space of a fair coin flip is {H, T}. The sample space of a sequence of three fair coin flips is all 23 possible sequences of outcomes: {HHH,HHT,HTH,HTT,THH,THT,TTH,TTT}. The sample space of a sequence of five fair coin flips in which at least four flips are heads is {HHHHH,HHHHT,HHHTH,HHTHH,HTHHH,THHHH}.

Answer 2

IF A COIN IS TOSSED, THERE ARE ONLY TWO POSSIBILITIES:

head or tail

Therefore,

S = {H,T}
