Question

From the sets given below, pair the equivalent sets: 

A = {1, 2, 3}, 

B = {t, p, q, r, s}, 

C = {α, β, γ}, 

D = {a, e, I, o, u}.

Answer 1

Note: Equivalent set are different from equal sets, Equivalent sets are those which have equal number of elements they do not have to be same.

 A = {1, 2, 3} 

Number of elements = 3 

B = {t, p, q, r, s} 

Number of elements = 5 

C = {α, β, γ} 

Number of elements = 3 

D = {a, e, I, o, u} 

Number of elements = 5 

Set A is equivalent with Set C and Set B is equivalent with Set D.
