(i) Outcome of getting a number 6 from ten separate slips is one. Therefore, probability of getting a number 6 = 1/10
(ii) Numbers less than 6 are 1, 2, 3, 4 and 5 which are five. So there are 5 outcomes. Therefore, probability of getting a number less than 6 = 5/10 = 1/2
(iii) Number greater than 6 out of ten that are 7, 8, 9, 10. So there are 4 possible outcomes. Therefore, probability of getting a number greater than 6 = 4/10 = 2/5
(iv) One digit numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9 out of ten. Therefore, probability of getting a 1-digit number = 9/10
