100 identical coins each with probability 'pp' showing up heads & tossed. If 0<p<10<p<1 and the probability of heads showing on 50 coins is equal to that ofheads on 51 coins, then the value of pp is?	Choose the correct choice.
A) 50/101	B) 51/103	C) 51/101	D) 63/111	E) 63/113
Let aa be the number of coins showing heads   Then, P(A=50)=P(A=51)P(A=50)=P(A=51)   ⇒10051/10150×P50×(1−P)50⇒10051/10151×P51×(1−P)49⇒10051/10150×P51×(1−P)50=10051/10151×P⇒51(1âˆ′P)=50P⇒P=51/101   51/101
