Let `A={a , b ,{c , d},\ e}` . Which of the following statements are false and why?
`(i){a , b , e} isub A`
`(ii){a , b , c}subA`
`(iii){phi}subA`

Text Solution

Verified by Experts

i) False
Since, `{a, b, e}` does not belong to `A`, `{a, b, e} sub A` this is the correct form.
ii) False
Here, `{a, b, c}` is not a subset of `A`.
iii) False
Since `phi` is a subset of `A`.
