Question

write all subsets of the set A=(x:x is a letter
in the word good).​

Answer 1

Answer:

{{G}, {O}, {D}, {G, O}, {O, D}, {G, D}, {G, O, D}, phi}

Step-by-step explanation:

total subsets 2^n

=2^3

=8

Answer 2

Since each element come from the word good, set A will be

{d, o, g} as elements cannot be repeated.

The subsets of {d, o, g} is

• 0 element: ∅
• 1 element: {d}, {o}, {g}
• 2 element: {d, o}, {o, g}, {g, d}
• 3 element: {d, o, g}

For your information,

∅, the empty set is always a subset. It is a basic property of set theory.

There will be 2ⁿ subsets where there are n elements in the set.
