Question

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 1

i) 1/10
ii) 1/2(i.e 5/10)
iii)2/5(i.e 4/10)
iv)9/10

Answer 2

Answer:

(i) 1/10

(ii) 1/2

(iii) 2/5

(iv) 9/10

Step-by-step explanation:

Total number of slips = 10

(i) Number of slips having no. 6 = 1

Probability = Number of slips having no. 6/total slips

                  = 1/10

(ii) Numbers of slips having less than no. 6 =5 (1,2,3,4,5)

Probability = slips having less than no. 6/total slips

                  = 5/10 =1/2

(iii) Number of slips having greater than no. 6 = 4( 7,8,9,10)

Probability = slips having greater than no. 6/total slips

                  = 4/10 = 2/5

(iv) Number of slips having single digit number = 9 (1,2,3,4,5,6,7,8,9)

Probability = slips having single digit number/total slips

                  = 9/10
