A) \[\frac{1}{2}\]
B) \[\frac{1}{4}\]
C) \[\frac{1}{8}\]
D) \[\frac{3}{8}\]
Correct Answer: D
Solution :
Let B be the event of getting exactly 1 head. |
\[\therefore \,\,\,\,\,\,\,\,B=\{HTT,THT,TTH\}\] |
\[\Rightarrow \,\,\,\,\,\,\,\,\,\,\,\,\,\,n(B)=3\] |
\[\therefore \] Required probability \[=\frac{3}{8}\] |
So, Option [d] is correct. |
