प्रश्न
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.
उत्तर
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`
