The sets T, F and W contain natural numbers and are defined as follows T= {multiples of 3 which are below 21}, F= {multiples of 4}, W = {factors of 12} Determine whether the following statements are true or false: a. 14 e F b. 24 ¢ T c. 1e (FU T) d. WU T= {1, 2, 4} e. (FOT) CW f. FOTOW=Ø

Q12. Fill in the missing element of B such that A = B. A = {7, 19, g, #, 2, 4, &, f, 16, 1, k} B = {#, 1, 7, __, k, 2, f, 19, g, 4, &}

Suppose you want to refute the statement: There are some natural numbers a, b, and c where a | b and b | c but a does not divide c.  Which of the following would be an appropriate strategy for you to employ? Group of answer choices Show specific values for a, b, and c where a | b and b | c and a | c. Show specific values for a, b, and c where a does not divide b and b does not divide c, but a | c. Show for any generic choices of a, b, and c that if a | b and b | c then a | c. Show for any generic choices of a, b, and c if a does not divide b and b does not divide c then a does not divide c.
