As we learnt
Equivalence Sets -
Two sets having same number of elements.
- wherein
eg. A= {H,T,P,V} and B= {1,2,3,4}
P has 2 elements as there are 2 roots of -5x+6=0 but +4x+5=0 has no real roots
Option 1)
P:{A,B,C,D,E} and Q:{Jan,Feb,Mar,April,May}
Option 2)
P:{x:x is a prime number on dice}
Q:{x:x is an even number on dice}
Option 3)
