Question

If the universal set U = {1, 3, 5, 7, 9, 11, 13, 15, 17} , B ={1, 3, 7,13,15}then find B​

Answer 1

Answer:

• If the universal set U = {1, 3, 5, 7, 9, 11, 13, 15, 17} , B ={1, 3, 7,13,15}then find B

Step-by-step explanation:

A'U[(AUB)nB'] = N

Step-by-step explanation:

A={1,3,5,7,11,13,15,17),

B={2,4,6,..,18}

N ={1,2,3,4,...}

i)A' = U - A

= {1,2,3,4,....}-{1,3,5,7,...,17}

={2,4,6,8,10,12,14,16,18,...}

ii)AUB={1,3,5,7,11,13,15,17}

U{2,4,6,...,18}

={1,2,3,4,5,6,7,8,...,17,18)

iv) B' =U-B

= {1,2,3,...}-{2,4,6,....,18)

= {1,3,5,...,17,19,20,21,...}

v)(AUB)nB'

= {1,2,3,4,....18}n{1,3,5,...,17,19,20,...}

={1,3,5,....,17}

iii) A'U[(AUB)nB']

=(2,4,6,8,10,...16,18,...)U{1,3,5,...,17}

= {1,2,3,5,6,....,}

=N
