(ii) A⊆D
(iii) D⊆B
(iv) D⊆A
(v) B⊆A
(vi) C⊆A

Answer 1

Answer:

i,ii,iii,v, are false

iv,vi are true

Answer 2

Answer:

Step-by-step explanation:

A = {a, b, c, d, e}, B = { c, d, e, f }, C = {b, d}, D = {a, e}

(i) C⊆B     FALSE     B does not Have b  while C has  

(ii) A⊆D    FALSE     A has extra elements than D  

(iii) D⊆B   FALSE     B does not Have a  while D has  

(iv) D⊆A    TRUE    

(v) B⊆A     FALSE     A does not Have f  while B has    

(vi) C⊆A     TRUE
