If V=vowelsinEnglishalphabet, write which of the following statements are true and which are false :
a,e,i∈V
Vowels in English alphabet are ={a,e,i,o,u}
V={a,e,i,o,u}
Here, a,e,i is a member of V, i.e., a,e,i∈V
Hence, the given statement is true.
Examine whether the following statements are true or false:
(i) {a, b} ⊄ {b, c, a}
(ii) {a, e} ⊂ {x: x is a vowel in the English alphabet}
(iii) {1, 2, 3} ⊂{1, 3, 5}
(iv) {a} ⊂ {a. b, c}
(v) {a} ∈ (a, b, c)
(vi) {x: x is an even natural number less than 6} ⊂ {x: x is a natural number which divides 36}
3. If V=vowelsinEnglishalphabet, write which of the following statements are true and which are false :
(i) c∈V
