Number of times an event occurs:Total number of times the activity is performed
Total number of times the activity is performed:Number of times an event occurs
Number of nonfavorable outcomes:Number of possible outcomes
Number of possible outcomes:Number of nonfavorable outcomes

Well I don't know how really to explain this without giving a direct answer...but http://www.mathgoodies.com/glossary/term.asp?term=experimental%20probability that should probably help you out

@jtvatsim what is it?

- anonymous

B?

- jtvatsim

Close, other way around. It's the number of times occurs to the total times.

- anonymous

A?

- Astrophysics

Yes, it was actually in the link

- anonymous

wait is it A or B?

- Astrophysics

"Experimental probability is the ratio of the number of times an event occurs to the total number of trials or times the activity is performed."

- anonymous

so B? @Astrophysics

- Astrophysics

C'mon man just read the sentence..

- anonymous

A

- Astrophysics

Yes

- anonymous

thanks :) sorry by the way, lol

This one should be pretty straight forward you want to find the amount of white beads in a total of 1000, so what is the original ratio out of a 100?

- anonymous

um, i dont get it

- Astrophysics

You're just suppose to multiply the original ratio by 1000

- anonymous

whats the original ratio?

- Astrophysics

Read your question and tell me what you think

- Astrophysics

It's not difficult see if you can figure it out first, out of a 100 trials how many times was white pulled out, just read the boxes.

- anonymous

270?

- Astrophysics

Yes, that's it! Because the original you have 27/100 multiply that by 1000 you get 270 :-)

- Astrophysics

That's all to it, not so hard right?

- anonymous

nopoe :)
