A fair coin is tossed till a head appears for the first time. The prob...
P(number of tosses is odd) = P(number of tosses is 1, 3, 5, 7 ...)
P(number of toss is 1) = P(Head in first toss = 1/2
P(number of toss is 3) = P(tail in first toss, tail in second toss and head in third toss)

P(number of toss is 5) = P(T, T, T, T, H)

So P(number of tosses is odd)
