Question

if U = {1,2,3,4,...12 ) A=( factors of 4) and B ={primes less than or equal to 10), then find AUB and
AnB.​

Answer 1

Step-by-step explanation:

A = { 1, 2, 4 }

[ as the universal set ends at 12, factors of 4 has to be less than 13 ]

B = { 2, 3, 5, 7 }

A U B = { 1, 2, 3, 4, 5, 7 }

A ∩ B = { 2 }
