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?

Solution:

We know that,

Probability = Number of favorable outcomes/Total number of outcomes

i) The outcome of getting a number 6 from ten separate slips is 1

Therefore, the probability of getting a number 6 = 1/10

ii) Numbers less than 6 are 1, 2, 3, 4, and 5. So, there are 5 possible outcomes.

Therefore, the probability of getting a number less than 6 = 5/10 = 1/2

iii) Numbers greater than 6 are 7, 8, 9, and 10. So, there are 4 possible outcomes.

Therefore, the 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, the probability of getting a 1-digit number = 9/10
