2K coins (K is an integer) each with probability P(O

  1. $\dfrac{K}{2K+1}$
  2. $\dfrac{K+1}{2K}$
  3. $\dfrac{K+1}{2K+1}$
  4. $\dfrac{2K}{K+1}$

C Correct answer
Explanation

For 2K tosses, equate the probabilities of K heads and K+1 heads. Cancelling the common binomial factor gives (1-P)/P = (K+1)/K. Solving yields P = (K+1)/(2K+1).
