Question

Tickets numbered 2, 3, 4, 5, ..., 100, 101 are placed in a box and mixed thoroughly. One ticket is drawn at random from the box. Find the probability that the number on the ticket is a number less than 16.

Answer 1

All possible outcomes are  2, 3, 4, 5................101.

Number of all possible outcomes = 100

Out of these, the numbers that are less than 16 = 2, 3, 4, 5,..................15.

Let E₂ be the event of getting a number less than 16.

Then,​ number of favourable outcomes =​ 14

∴ P (getting a number less than 16) = `14/100 = 7/50`
