Question : 23

Total: 40

Given that

\mu=\{1,2,3, \ldots 10\}

\mathrm{M}=\{2,3,5,7\}

, where M is a subset of

\mu

. List the members in

\mu

that are not in M.

\{1, 4, 6\}
\{2, 4, 6, 8, 10\}
\{2, 4, 6, 8\}
\{1, 4, 6, 8, 9, 10\}

Solution:

Concept:

Find the complement of set

M

in

\mu

, i.e. list all elements of

\mu

that are not in

M

.

Explanation:

\mu = \{1,2,3,4,5,6,7,8,9,10\}

M = \{2,3,5,7\}

Remove the elements of

M

from

\mu

:

1,4,6,8,9,10

remain.

Thus,

\mu \setminus M = \{1,4,6,8,9,10\}

.

Answer:

\{1,4,6,8,9,10\}

, which is option D.
