Answer:

Tubular form of sets is also roster method where the elements are listed as described in the statement form.

1) A= the set of whole number less than 4

Whole numbers are 0 and natural numbers 1, 2, 3, 4, ...

A = {0, 1, 2, 3}

2) B= the set of prime numbers less than 14

Prime numbers are numbers whose factors are exactly two, the number itself and 1.  Note that one the number 1 is not a prime number because it does not have two distinct factors.

B = {2, 3, 5, 7, 11, 13}

3) C= the set of first three days of the week

C= {Sunday, Monday, Tuesday}  ⇒ in the religious calendar

or

C = {Monday, Tuesday, Wednesday)  ⇒ the modern work-week calendar

4) D= (x/x is an even number less than 15}

The even numbers are numbers with ones-digit 0,2,4,6,8.

The even numbers less than 15 are: 2,4,6,8,10,12,14

D = {2,  4, 6, 8, 10, 12, 14}
