Question

find p(A) and,if A={1,2,3,4}

Answer 1

Hey dear here is your answer!!!!!!

Power Set={{1,2,3,4},{1,2,3},{1,2,4},{1,3,4},{2,3,4},{1,2},{1,3},{1,4},{2,3},{2,4},{3,4},{1},{2},{3},{4},{}}Power Set={{1,2,3,4},{1,2,3},{1,2,4},{1,3,4},{2,3,4},{1,2},{1,3},{1,4},{2,3},{2,4},{3,4},{1},{2},{3},{4},{}}

Hope it helps u dear..

Answer 2

Answer:

$P(A)=\{\{\}, \{1\}, \{2\}, \{3\}, \{4\},\{1,2\},\{1,3\}, \{1,4\},\{2,3\},\{2,4\},\\\{3,4\},\{1,2,3\},\{1,2,4\},\{1,3,4\},\{2,3,4\},\{1,2,3,4\}\}$

Step-by-step explanation:

The given set is

$A=\{1,2,3,4\}$

We need to find P(A). It means we need to find the power set of set A.

A power set of a set is set of all subset of that set.

Empty set is the subset of all sets.

So, the power set of set A is

$P(A)=\{\{\}, \{1\}, \{2\}, \{3\}, \{4\},\{1,2\},\{1,3\}, \{1,4\},\{2,3\},\{2,4\},\\\{3,4\},\{1,2,3\},\{1,2,4\},\{1,3,4\},\{2,3,4\},\{1,2,3,4\}\}$
