निर्दिष्ट परीक्षण का प्रतिदर्श समष्टि ज्ञात कीजिए।

एक पासा दो बार फेंका गया है।

When a die is thrown, the possible outcomes are $1,\,2,\,3,\,4,\,5,$ or $6$.

When a die is thrown two times, the sample is given by $S =\{(x, y): x , y =1,2,3,4,5,6\}$

The number of elements in this sample space is $6 \times 6=36,$ while the sample space is given by :

$S=\{(1,1),\,(1,2),\,(1,3)$, $( 1,4),\,(1,6),\,(2,1)$, $(2,2),\,(2,3),\,(2,4)$, $(2,5),\,(2,6),\,(3,1),$ $(3,2),\,(3,3),\,(3,4)$, $(3,5),$  $(3,6),\,(4,1)\,,(4,2)$, $(4,3),\,(4,4),\,(4,5),\,(4,6)$, $(5,1)\,,(5,2),$ $(5,3)\,,(5,4)\,,(5,5)$, $(5,6),\,(6,1),\,(6,2)$, $(6,3)$, $(6,4),\,(6,5),\,(6,6)\}$
