### Probability.

Today in math class we did :

If we had to flip a coing there is a 50% chance that we will get heads or tails. A way we can simplify that is

Questions:

What is the probability of rolling a 60 with a standard die

*P( ) means the probability of the thing inside the brackets happening

the letters s.n.o.w are placed in a bag
a) what is P(w) when drawing 2 letter?
1:4 25% 1
-
4

b) P(constanant) out of the bag
3:4 3 75%
-
4

There are 10 marbles 3 BLUE
1 GREEN
6 RED

a) p(red)

6
6:10 60%
10

P(red, blue , green)
- this is a certain event !

mountain are in a bag?
a PCN
B PC constanant
c letter
d Pc - number

1. Nice job Lizelle! You explained everything well. It was really really nice and neat. But the Green and 6 Red's font is really big. Make it a little lower next time. You also probably needed a link. Everything else was perfecto. :)

2. Good job. You explained everything well. I like the video because it talks about the subject. Next time you should check the spelling and grammar. I found some mistakes. Like the word was mountain and you put v instead of u, I think the C was suppose to be ( ). Other than that you did good.

3. Good Post Lizelle!!! You explained what we did in class but there were a one or two flows. One of the questions had too small font so it was hard to read. Thanks for posting a video since it helps understand it more(: Everything else was good. Keep up the good work(:

4. Good Job ! You explained it really well. Some of your fonts are too big . I liked how you put a video to make people more know the lesson ! Anyways Good job ! :D

5. Good job Lizelle!! You explained what we did very goodly... Some of the font you had were too big though, and the question font was too small to read. I like the pictures, colours and video. Good job again!! :)

6. Good job. Good explanation of probability. The font was way to big. Tone it done next time please. Try to put a link in.

8. Good job, Lizelle! I liked your diagrams and your video. I thought that you examples were easy to understand and it showed that you understood probability. But next time, you should try and get a video and make your font size and color enough so that it's easy to read. But overall, you did a good job!

9. Good Job Lizelle! very well explained and good job on putting a video, but i think some of your words are toob big but other than that GOOD JOB!

10. Great job! Your blog post was pretty good, and there was lots of colour, so it wasn't dull. I liked the diagrams, but some of them weren't needed and some of them weren't clear. You should watch out for typos in your post. For example, what is a coing? Are you advertising for PC (President's choice). Oh yeah, the probability of rolling a 60 with a standard die is 0%. Other than that, great post! :)

11. Good job Lizelle! I liked the diagrams you gave us. I also liked that you posted up a video for us to watch but it was a little long which could possibly get us bored. So I think that next time you should choose a shorter video. I liked your choice of colour because they weren't too bright. You should be aware of the size of font you used because some were too big yet some were too small. I really liked that you showed us the different ways to show probability. But overall, excellent job.(:

12. Lizelle, I liked how you included good font, color, diagrams, and a good video. You also showed what we did in a good simple way.

13. Good Job Lizelle!The pictures and colors were nice and you should put the font smaller for some of the words. The way you explained probability was very well. Good Job!

14. Good Job Lizelle! Well explained.Nice use of colours except grey was a little light. Good job putting a video, and I like the writing that's in the pictures. :D Good job. :D

15. niiice job!!
