Option A
Option B
Option C
Option D
Solution
Clearly the coins are distinguishable in the sense that we can speak of the first coin and the second coin. since either coin can turn up Head $(H)$ or Tail $(T)$, the possible outcomes may be
Heads on both coins $=( H , \,H )= HH$
Head on first coin and Tail on the other $=( H ,\,T )= HT$
Tail on first coin and Head on the other $=(T, \,H)=T H$
Tail on both coins $=(T,\, T)=T T$
Thus, the sample space is $S =\{ HH ,\, HT , \,TH , \,TT \}$
