If d is the set of whole numbers that are whole numbers less than 5, choose the selection below that correctly shows this set in roster and set­builder notation.
a. d = {0, 1, 2, 3, 4}; d = {x | x is a whole number, x < 5}
b. d = {0, 1, 2, 3, 4, 5 , 6, 7, 8, 9, 10}; d = {x < 5}
c. d = {0, 1, 2, 3}; d = {x | x is a whole number, x < 5}
d. d = {6, 7, 8, 9, 10}; d = {x < 5}

A. D = {0, 1, 2, 3, 4}; D = {x | x is a whole number, x < 5}

Step-by-step explanation:

In roster form we write the elements of a set separated by commas and enclose them in flower bracket {}.

While, in set builder form we write the properties of the elements of a set by using mathematical symbol and also enclosed them in {},

∵ Whole numbers are,

0, 1, 2, 3, 4, 5, 6,

Thus, the whole numbers less than 5 are,

0, 1, 2, 3, 4

If D is the set of whole numbers less than 5,

Then roster form of D,

D = { 0, 1, 2, 3, 4 }

And, Set builder form of D,

D = { x | x is a whole number, x < 5 }

Hence, OPTION A is correct.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
