Question

if U={1,2,3,7,8,9,10,11,12},P={1,3,7,10},then verify (P')'=P with explaination ​

Answer 1

p = 1 3 7 10

p'= 2 4 5 6 8 9

(p')' = ( 2 4 5 6 8 9 )'

= 1 3 7 10

answer

Answer 2

Answer:

Step-by-step explanation:

P={1,3,7,10} and Q={1,2,3,7,8,9,10,11,12}

=> P is a subset of Q set..

Then (P)'= {Q}-{P} = {1,2,3,7,8,9,10,11,12} - {1,3,7,10} = {2,8,9,11,12} = (P)'

Then

(P')'= {Q}-{P'} = {P} (proved)
