Let `A={{1,2,3},\ {4,5},\ {6,7,8}}dot` Determine which of the following is true or false:
`(i)1 in A`
`(ii){1,2,3}subA`
`(ii){6,7,8} in A`

Text Solution

Verified by Experts

i) False
Since, `1` is not an element of `A`.
ii) True
Hence, `{1, 2, 3} in A` is the correct form.
iii) True
Hence, `{6, 7, 8} in A`.
