If `U= {x:xle10,"x"inN}A={x:"x"inN,x " is prime"}B= {x:"x"inN,x " is even"}` write `A cap B` in roster form.

Text Solution

Verified by Experts

The correct Answer is:
`u={1,2,3,4,5,6,7,8,9,10} , A={2,3,5,7,11,13,..},B={2,4,6,8,10..}`
`therefore A capB = {2,3,5,7,11,13,...} cap {1,3,5,7,9,11,...}={} emptyset`
