Which of the following sets are empty sets? Why? (a)A = { x|x is a whole number greater than zero } (b)B = { a|a - 9 = 0, a ∈ N } (c) C = { x|10x – 1 = -11, x ∈ N } |

Answer» -step explanation:A and C would be empty sets.1. set A has no solution qs natural number BEGIN from 1. A= Ø2. set B has solution 0 i.e B= {0}3. for set C . X value would be 0.4, which is not a natural number so C= Ø |
