Question

Complete the following method.

    /**
     * This method calculates the probability of tossing a 
     * coin n times and and getting n heads.
     *
     * The probability of getting a single head is 0.5.  The
     * probability of getting two heads is 0.5*0.5.
     * The probability of n heads is 0.5*0.5*...*0.5 (where there are
     * n terms in the product).
     *
     * @param n      The number of tosses
     * @return       The probability of n heads in n tosses
     */
    public static double probabilityOfHeads(int n)
    {





    }
    

Answer 1

public static double probabilityOfHeads(int n) {
  double d = 1;
  for(int i = 0;i<n;i++){
    d = d * 0.5;
  }
  return d;
}
