Question

Write down all possible subsets of set P using correct set notation.

Answer 1

i know it f,h,i,s but how can i write it using the correct set notation.

Answer 2

can u figure this out 24+z=43

Answer 3

would it be 24+ 19 = 43

Answer 4

do you know about "power set"

Answer 5

no

Answer 6

ok...
so you want to list down all the subsets of P.

can you tell how many elements P has ?

Answer 7

4 elements

Answer 8

did i get it

Answer 9

yes. now to list down subsets-
a subset of P is just a another set formed with elements from P

Answer 10

P = {f , h, i, s}

Answer 11

S1 = { f }

is it a subset of P ?

Answer 12

it is, because P has the element "f"

Answer 13

S2 = { a }

can you tell if it is a subset of P ?

Answer 14

no it not because P dont have the element of ''a''

Answer 15

thats right !!

Answer 16

so you know what is a subset of P and what is not a subset! so try listing the possible subsets now...

start with empty set :
{}

{f}
{h}
{i}
{s}

{f, h}
{f, i}

........

can you try listing the rest of possible subsets ?

Answer 17

ok

Answer 18

P= {} {f} {h} {i} {s} {f,h} {f,i} {f,s} {s,f} {s,i} {s,h} {i,f} {i,s} {i,h} {h,i} {h,s} {h,f} hope I did right

Answer 19

looks you're on right track !! two things i notice -
1) you listed only upto 2 element subsets. you did not list 3 element subsets, for ex, below are also subsets of P :
{f, h, i}
{f, h, s}
....

2) there are some redundant sets in your listing. see, {f, h} and {h, f} are same sets. you shouldnt list them twice... !

Answer 20

oh ok

Answer 21

how it look now P= {} {f} {h} {i} {s} {f,h} {f,i} {f,s} {s,f} {s,i} {s,h} {i,f} {i,s} {i,h} {h,i} {h,s}
{f, h, i} {f, h, s} {f,h,i,s}
