Probability

In an event organized by my friend DJ Shon at Mani Square during the Durga pujas there was a particular game event that required contestants to choose the Joker from a pack of cards. The game was announced and a group of 5 college goers surrounded the game table. There were 5 cards laid down on the table and being the generous person Shon is, he guaranteed that one of the participants would surely pick a Joker. However, he is stringent enough to allow at most 1 Joker in the pack of 5 cards laid down at the table. The cards are, of course, laid face down on an opaque table with nobody except the dealer knowing which card is the Joker. Of course, I assume the dealer is not biased!
