A die is thrown repeatedly until a six comes up. What is the sample space for this experiment ?
In this experiment, six may come up on the first throw, the second throw, the third throw and so on till six obtained.
Hence, the sample space of this experiment is given by
$S =\{6,(1,6),\,(2,6),$ $(3,6),\,(4,6),$ $(5,6),\,(1,1,6),\,(1,2,6)$, ...... , $(1,5,6),\,(2,1,6),\,(2,2,6)$, ....... $(2,5,6)$, ........ , $(5,1,6),\,(5,2,6)$, .......... $\}$
