A special lottery is to be held to select a student who will live in the only deluxe room in a hostel.
There are 100 Year- Ill, 150 Year-II, and 200 Year-I students who applied. Each Year-III’s name is placed in
the lottery 3 times; each Year-II’s name, 2 times; and each Year-I’s name, 1 time. What is the probability
that a Year-III’s name will be chosen?

• no of third year stud name:300
  no of 2nd year stud. name:300
  no of 1st yr stud name:200
  total:800
  probability for 3rd year stud=300/800=3/8.

• @vigneshwary: bcz there are 150 students in 2nd yr.
  nd each student's name is written twice.
  hence 150*2=300
