Question

Let $U$ be the set of all people and $M=$ { Males}, $S=${College Students }, $T=${Teenagers}, $W=${People having heights more than five feet }. Express the following in the notation of set theory.

College students having heights more than five feet.

• A. $S\cap W$
• B. $M\cap S$
• C. $M\cap W$
• D. none of these

Answer 1

The correct option is A $S\cap W$

Here we have to write down the set of all those people having both the properties: (1) college students, (2) people having their height more than five feet. Hence it is the set consisting of common elements of the $SandW,$ that is the set $S\cap W.$
