Fill in the blanks with to make each statement true.

i. {3} ---- {0, 2, 4, 6}

ii. {a} ---- {a, b, c}

iii. {8, 18} ---- {18, 8}

iv. {d} ---- {a, b, c}

i. {3} {0, 2, 4, 6}

because, here the first set contains only one element 3, which is not present in the second element. Hence we are using “does not belong to” symbol to represent it.

ii. {a} {a, b, c}

because, here the first set contains only one element a, which is present in the second element. Hence we are using “subset” symbol to represent it.

iii.{8, 18} {18, 8}

because, here the first set contains elements 8,18 which are present in the second element. Hence, they are equal sets, we are using “subset” symbol to represent it.

We know that all equal sets can be subsets of each other as well.

iv. {d} {a, b, c}

because, here the first set contains only one element d, which is not present in the second element. Hence we are using “does not belong to” symbol to represent it.
