A) \[\frac{63}{256}\]
B) \[\frac{1}{1024}\]
C) \[\frac{2}{205}\]
D) \[\frac{9}{64}\]
Correct Answer: A
Solution :
Probability for a head \[=\frac{1}{2}i.e.,\,\,p=\frac{1}{2}\] \[\therefore \]\[q=\frac{1}{2}\] in a toss. Required probability \[{{=}^{10}}{{C}_{5}}{{\left( \frac{1}{2} \right)}^{5}}{{\left( \frac{1}{2} \right)}^{5}}=\frac{63}{256}\].
