Answer 1

Answer:

set A ={45,46,47,48,49,50,51,52,53,54,55}

set B={46,48,50,52}

set C={45,48,51,54,57}

Step-by-step explanation:

A U C={45,46,47,48,49,50,51,52,53,54,55,57}

A π C={45,48,51,54}

A U B={45,46,47,48,49,50,51,52,53,54,55}

A π B={46,48,50,52}

C-A={57}

A-C={46,47,49,50,52,53,55}
