Options:

A .

\frac{3}{2^{14}}

B .

\frac{5}{2^{14}}

C .

\frac{7}{2^{13}}

D . None of the above

Answer: Option C

C

13 losses from 14 can be selected in $^{14} C_{13}$ ways i.e.14

At any of the tosses only 2 events can happen win or loss hence total sample space: $2^{14}$

P(E)= $\frac{14}{2^{14}}$
