Answer 1

Answer:

{p},{q},{r},{p,q},{q,r},{p,r}{},{p,q,r}

Step-by-step explanation:

The set of all the subsets of a set"is a power set

Basically we collect all possible subsets of a set.

Example: For the set {a,b,c}:

• The empty set {} is a subset of {a,b,c}

• And these are subsets: {a}, {b} and {c}

• And these are subsets: {a,b}, {a,c} and {b,c}

• And {a,b,c} is actually a subset of {a,b,c} too

Answer 2

Answer:

subsets:{p},{q},{r},{},{p,q,r}{p,q},{p,r},{q,r}

Power set is set of all subsets of a set
