To begin -- I don't know the answers for 8, 10, 11, 13-16.

You didn't post # 9.

Do you have an error in number 5?

Other than that, I found only one of your answers to be correct. Number 1 is correct.

Since I may be wrong, I urge you to go back over your lesson to make sure you still think your answers are correct.

Then repost these questions along with your answers -- but post no more than five questions and answers in each post. Do not put any name on it so that real math teachers will respond!

Here are my answers:
1A 2C 3C 4A 5B 6C 7B 8C 10D 11A 12A 13B 14C 15C 16A

They should have posted the answers to #4 and #5 in the form a:b, that is how odds are expressed.
After all , they did it correctly in #7

Remember, odds are similar to probabilities.
the odds in favour of some event
= prob(the event happens) : prob(event does not happen)
