### PROBLIBILITY

You have a cup it has four coins in it there is a quarter, a dime,a nickel, and a penny

You draw one coin out of the cup then put it back then draw another coin. If the two numbers you drew from the cup add up evenly then you win if they add up oddly then you lose.

P(even sum)= 10/16 or 5/8 or 62.5%
P (odd sum)= 6/16 or 3/8 or 37.5%

A coin is flipped and a six sided die is rolled. these two events are called independent events. Independent Events- The outcome of one event has no effect on the outcome of another event.

Sample Space- All possible outcomes of an experiment.

A coin is flipped and a six sided die is rolled.

A) use a table/ chart to list the possible outcomes

B) How many possible outcomes are there

C) Write the sample space for this combination of events

Possible: 12
Sample Space:(H-1)(H-2)(H-3)(H-4)(H-5)(H-6)(H-7)(H-8)(H-9)(H-10)(H-11)(H-12)
(T-1)(T-2)(T-3)(T-4)(T-5)(T-6)(T-7)(T-8)(T-9)(T-10)(T-11)(T-12)

I think this video will really help anyone who doesn't understand how to do probability.

1. Nice post Summer. You explained everything good just like in class. But next time you should put the homework with the whole post.

2. Good post, Summer! You did a good job of explaining what we did in class and the video helped me. Next time, try to put the homework with the scribe post.

3. Nice post Summer, you should have made the important words a different font color.

9. Nice post Summer. I looks really neat, but next time add the homework. Other than that great job.

10. Great job Summer. Your post is very neat and eazy to understand. You exlpain on how to do probability very good.But if you coudl have put colour for importan things or make the bigger on the importan things and if you added the homeweork it could have been better.But it was still a good post!

11. Good job, Summer. I like the pictures that you posted. Next time you should check the spelling and post the homework. Other than that, everything was fine.

17. Great job Summer! I like how you explained what probability is. It's really easy to understand. Nice video and pictures by the way. Next time maybe you should put up a link.

18. Great job Summer! It was very descriptive. But next time I think you should change the color or the font of the important facts.

19. Great post, Summer. I really liked the pictures you posted, It's very helpful and also the video. Next time you should post up the homework and also spell check before publishing. Other than that. Good job.
