Question

If A={x:x is a prime and x<10},B={x:x is a factor of 6}. then find A intersection B,A union B and A-B​

Answer 1

Step-by-step explanation:

A={2,3,5,7}

B={1,2,3,6}

A intersection B = { 2,3}

A union B = { 1,2,3,5,6,7}

A-B= {5,7}

Answer 2

Answer:

A={2,3,5,7}

B={1,2,3,6}

AΩB={2,3}

AUB={1,2,3,4,5,6,7}

A-B=5,7
