There are two schemes in Vodafone mobiles.
First scheme :1 paise per second,
Second scheme :50 paise per minute,

Following conditions are given -
1) In second scheme, second minute will be started at 0:60 or 1:00,
2) 0 sec. call means to call and cut it abruptly when timer reads 0:00, this is equivalent to a call of 1 sec.
3) In first scheme 0:14 means 15 sec.

The probability that first scheme is more profitable over second in a call ranging from 0:00 (1 sec.) to 3:20 (201 sec.) is ?

• According to the first scheme, cost=201 paisa
  according to the second scheme ,cost=150+50=200 paisa.
  so the probability that the first scheme is more profitable over second scheme is "zero".
