Question

Let A={2,3,5,7, 11, 13} and
B = {5,7,9,11,15}
u= {2, 3, 5, 7, 9, 11, 13, 15}
Find
1 AUB
2) A intersection B
3) A'
4) B’

Answer 1

Answer:

given,

A={2,3,5,7, 11, 13}

B = {5,7,9,11,15}

u= {2, 3, 5, 7, 9, 11, 13, 15}

now,

AUB={2,3,5,7,9,11,13,15}

A intersection B={5,7,11}

A'={9,13,15}

B'={2,3,13}
