Numbers 1 to 10 are written on ten separate slips (one number on one s

1.	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.
Answer» (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

(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
