Question

let A = {x:x is a prime number less than 50} and B = {x:x is an odd number less than 50} find A-B with the help of venn diagram​

Answer 1

Answer:

In set A={2,3,5,7,11,13,17,19,23,29,31,37,41,43,47}

In set B={1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31,33,35,37,39,41,43,45,47,49}

So A–B ={2}

IN SHORT

2 IS ONLY EVEN PRIME NUMBER SO AFTER SUBTACTION ALL ODD NUMBERS WILL BE CANCELLED AND ONLY 2 IS LEFT
