Question 180428: I am having trouble understanding disjunctions. Can you give me some pointers to help me figure it out?

Answer by Mathtut(3670) (Show Source): You can put this solution on YOUR website!
For a disjunction (or) to be true, EITHER or BOTH facts must be true
:
the only time it is false is when both statements are false.
:
for instance:
:
1. "Blue is a color or 7 + 3 = 10."
(T or T = T) Since both facts are true, the entire sentence is true.

2. "One hour = exactly 55 minutes or one minute = exactly 60 seconds."
(F or T = T) Since the second fact is true, the entire sentence is true.

3. "3 + 4 = 6 or all dogs meow."
(F or F = F) Since both facts are false, the entire sentence is false.

4. "The word cat has 3 letters or the word dog has four letters."
(T or F = T) Since the first fact is true, the entire sentence is true.
God Bless!!!
