german

Answer:

M-T={even numbers}

Step-by-step explanation:

We are given that

\varepsilon={x:2\leq x\leq 30,x is an integer}

M={even numbers}

P={Prime numbers}

T={odd  numbers}

We have to find M-T

M\cap T=\phi

We know that

A-B=A-A\cap B

Using the formula

Then, we get

M-T=M-M\cap T

M-T={even numbers}-\phi

M-T={even numbers}
