If B = {5, 4, 6, 8}, Then Number of Proper Subsets of B = ____.

If B = {5, 4, 6, 8}, then number of proper subsets of B = ____.

Fill in the Blanks

If B = {5, 4, 6, 8}, then number of proper subsets of B = 2⁴ – 1 = 2 × 2 × 2× 2 – 1 = 16 – 1 = 15.

Express the following sets in roster form:

F = Set of factors of 24.

Express the following sets in set- builder notation (form):

`{1/3, 1/4, 1/5, 1/6, 1/7, 1/8}`

Given: D = {x: x is a prime number less than 25}. Write the set in roster form.

State whether the given pair of set is equal or equivalent.

A = {first four natural numbers} and
B = {first four whole numbers}

State true or false of the following statement:

All examples of the empty set are equivalent.

State true or false of the following statement:

If M = {1, 2, 4, 6} and N = {x : x is a factor of 12} ; then M = N.
