उत्तर
i) There are 10 slips in the box. However, 6 is written only on 1 slip.
Probability of getting a number 6 = `1/10`
ii) The numbers less than 6 are 1, 2, 3, 4, 5.
Probability of getting a number less than 6 = `5/10 = 1/2`
iii) The numbers greater than 6 are 7, 8, 9, 10.
Probability of getting a number greater than 6 = `4/10 = 2/5`
iv) There are 9 numbers which are single digit numbers.
1, 2, 3, 4, 5, 6, 7, 8, 9
Probability of getting a single digit number = `9/10`
