Question
Match each of the set on the left in the roster form with the same set on the right described in set-builder form :
|
(i) {1,2, 3, 6} |
(a) {x : x is a prime number and a divisor of 6} |
|
(ii) (2, 3} |
(b) {x : x is an odd natural number less than 10} |
|
(iii) (M, A, T, H, E, I, C, S} |
(c) {x : x is natural number and divisor of 6} |
|
(iv) (1,3,5, 7, 9} |
(d) {x : x is a letter of the word MATHEMATICS} |
Solution
(a) { x : x is a prime number and a divisor of 6} = {2, 3}
(b) { x : x is an odd natural number less than 10} = {1, 3, 5, 7, 9}\
(c) { x : x is a number and divisor of 6} = {1, 2, 3, 6}
(d) { x : x is a letter of word MATHEMATICS} = {M, A, T, H, E, T, I, C, S}
∴ The matching is :
