Which of these are propositions? What are the truth values of those that are propositions?
 a) Do not pass go. 
b) What time is it? c) There are no black flies in Maine. d) 4+x=5.
 e) The moon is made of green cheese. f) 2n ≥ 100. Propositions are a, c, and e, but propositions are not b, d and f because they... show more Which of these are propositions? What are the truth values of those that are propositions?


a) Do not pass go.

b) What time is it?
c) There are no black flies in Maine.
d) 4+x=5.

e) The moon is made of green cheese.
f) 2n ≥ 100.

Propositions are a, c, and e, but propositions are not b, d and f because they are not declarative sentences.
Hence, a is F, c is T, and e is F.
