5th hour 2-7
to find the probability with replacements you take the number of over the total number of then with the replacement it will be the same as the first, with out the replacement you find the probability except you subtract the the number of from the total all together and find the probability with the new total number. to find the compound probability with replacements you take to different probabilities and multiply, but to find compound probabilities without replacements you take one probability and get another that is a probability without replacements and multiply.

Great job. you might want to add some examples though. But altogether it was great!!!
That was great. examples would have been more helpful but oh well. Good way to explain.
Nice examples wait there where none. Oh well I'll get over it. Nice way of explaining. "Good Job *clapping* Encore Encore"
Nice explaining! But like Carly said, add some example so people truly understand it!
Good job. You explained it better than i could have. Examples would have been very nice...O well tho.
nice Trace!!
lol
that was great
Good job explaining!! Like Lacie and Carly said just add some examples!
u should add some examples next time!!! :):)
Great job though!
Add some examples and you're good to go! ! :))
An example would be...
There are marbles in a bag. Three red, two yellow, and eight blue. What is the probability of picking a red marble then a yellow marble?
Well, first find out the total number of marbles, (13).
Then take the number of red marbles, (3) and put it over 13. Like this, 3/13.
Next, find the total number of yellow marbles (2)and put it over 13.
Simplify if possible.
Your equation should look like this so far.
3/13 * 2/13
Multiply across so your equation will end up like this
3/13 * 2/13 = 6/169
Okay, I hope I did a good job!!
