In a hotel, rooms are numbered from 101 to 550. A room is
chosen at random. What is the probability that room number
starts with 1, 2 or 3 and ends with 4, 5 or 6?
Answer Posted / guest
There are total 450 rooms.
Out of which 299 room number starts with either 1, 2 or 3.
(as room number 100 is not there) Now out of those 299
rooms only 90 room numbers end with 4, 5 or 6
So the probability is 90/450 i.e. 1/5 or 0.20
