Is it true w is the set of (s,w,n,t,c)

umka21 [38]

Answer:

{w} is the SUBSET of {s,w,n,t,c}

Step-by-step explanation:

SUBSET: Any set P is called a SUBSET of a set Q is ALL ELEMENTS of P are in the set Q.

i.e P ⊂ Q

Here, the given set Q = {s,w,n,t,c}

Also, set P = {w}

Now,as the element w of set P is also an element of set Q.

⇒ P is the SUBSET of Q

⇒ P ⊂ Q

⇒ {w} ⊂ {s,w,n,t,c}

Hence, {w} is the SUBSET of {s,w,n,t,c}.
