Option A

Option B

Option C

Option D

Solution

The box contains $2$ red balls and $3$ black balls. Let us denote the $2$ red balls as $R_{1}, R_{2}$ and the $3$ black balls as $B _{1}, \,B _{2},$ and $B _{3}$

The sample space of this experiment is given by

$S =\{ TR _{1}, \,TR _{2},\, TB _{1}$, $TB _{2},\, TB _{3}$, $H1 , \,H 2,\, H 3$, $H 4,\, H 5,\, H 6\}$
