Arthur was walking in the park when he saw his friend, Daniel. He saw that Daniel had his eyes closed. Arthur asked Daniel if he was OK and Daniel said he was very tired because he had carried a tree for five miles. Arthur told Daniel he was either a liar or completely mad! However, Daniel was able to prove he did, in fact, carry a tree for five miles. How was that possible?
There are hundred red gems and hundred blue gems. The blue gems are priceless while the red gems equal wastage. You have two sacks one labeled Heads and the other Tails. You have to distribute the gems as you want in the two sacks. Then a coin will be flipped and you will be asked to pick up a gem randomly from the corresponding sacks.
How will you distribute the gems between the sacks so that the odds of picking a Blue gem are maximum?
