બે સિક્કાઓ, એક રૂપિયાનો સિક્કો અને બીજો બે રૂપિયાનો સિક્કો એકવાર ઉછાળો અને નિદર્શાવકાશ શોધો.

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 $S =\{ HH ,\, HT , \,TH , \,TT \}$
