#### Question

If A = {*x*:* x* is a natural number}, B ={*x*:* x* is an even natural number} C = {*x*:* x* is an odd natural number} and D = {*x*:* x *is a prime number}, find

A ∩ B

#### Solution

A = {*x*:* x* is a natural number} = {1, 2, 3, 4, 5 …}

B ={*x*:* x* is an even natural number} = {2, 4, 6, 8 …}

C = {*x*:* x* is an odd natural number} = {1, 3, 5, 7, 9 …}

D = {*x*:* x *is a prime number} = {2, 3, 5, 7 …}

A ∩B = {*x*:* x* is a even natural number} = B
