A box contains tickets numbered 01 to 100. What is the probability that a ticket selected at random will have number with a tenth digit of 5?
  1. 1/5
  2. 9/10
  3. 1/10
  4. ½
Explanation
Answer C: The tenth digit of 5 is 05, 15, 25 ....., and 95. i.e. 10 possible numbers out of 100 numbers.
Probability P = favourable events for success / total possible events = 10/100 = 1/10.

Key takeaway: Probability is the chance of the occurrence of an event. It is the ratio of favourable events for success and total possible events.
