see, the logic here is the last person will either get his own ipod or the ipod of the last person.the probability of the picking the ipod of the 1st person is equal to the prob of picking the ipod of the last personhere's how:if you think over the arrangement closely enough, you will observe that whenever a person picks up the ipod of the 1st person... thereafter everyone gets their own ipod... if the 1st person gets his ipod , everyone will get their ipod.and if he misses his ipod, the rest of the people will get their ipod only from the time a person picks up the ipod of the 1st person.So, the last person gets his own ipod or the ipod of the 1st person.therefore prob: 1/2
Just becoz the last person has to get one of the two options, how is it that the probability of getting either one of them wud be 1/2 ? ?
