Question

State whether the given pair of sets are equal or equivalent:

(iv) A={days of the weeks starting with letter S} and

B={days of the weeks starting with letter T}

Answer 1

Step : Check whether the given pair of sets are equal or equivalent

Given:

A = {days of the weeks starting with letter S}

= {Saturday, Sunday} in roaster form and

Number of elements in set A = 2

B = {days of the weeks starting with letter T}

= {Tuesday, Thursday} in roaster form

Number of elements in set B = 2

$\therefore$ only the number of elements are equal in set A and set B.

And we know that two sets are said to be equivalent, if they have equal number of elements in them.

Hence, set A and set B are equivalent set.
