(b) 7 ∈ {1,2,3,4,5,6,7,8,9,10}
(c) 7 ∉ {1,2,3,4,5,6,7,8,9,10}
(d) {7} M {1,2,3,4,5,6,7,8,9,10}

Answer 1

Option {b} is the correct answer......

Answer 2

Answer:

7 ∈ {1,2,3,4,5,6,7,8,9,10}

Step-by-step explanation:

7 ∈ {1,2,3,4,5,6,7,8,9,10}

is correct as 7 belongs to {1,2,3,4,5,6,7,8,9,10}

{7} ∈ {1,2,3,4,5,6,7,8,9,10}

here  {7} is a set

and {7}  is Proper subset of {1,2,3,4,5,6,7,8,9,10}

{7} ⊂ {1,2,3,4,5,6,7,8,9,10}

7 ∉ {1,2,3,4,5,6,7,8,9,10}

Not correct as 7 belongs to {1,2,3,4,5,6,7,8,9,10}

{7} M {1,2,3,4,5,6,7,8,9,10}
