There is a die with 10 faces. It is not known that fair or not. 2 captains want to toss die for batting selection. What is the possible solution among the following?
a) If no. is odd it is head, if no. is even it is tail
b) If no. is odd it is tail, if no. is even it is head
c) Toss a die until all the 10 digits appear on top face. And if first no. in the sequence is odd then consider it as tail. If it is even consider it as head.

• the solution is:
  it is not known that the die is fair o r not.
  so we have to check whether it is fair or not
  so, to check..we have to toss until the ten digit appears on the top..
  then selection of head or tail is done.
  hence the answer is (c).
