Numbers 1 to 10 are written on ten separate slips (one number on one slip), kept in a box and mixed well. One slip is chosen from the box without looking into it. What is the probability of: (i) getting a number 6. (ii) getting a number less than 6. (iii) getting a number greater than 6. (iv) getting a 1-digit number.

(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
