9. A
10. D
First of all, Grace and idk, u guys are the ones on this cheating site so stop telling others something u should do yourself! Get over it. We make our own decisions, NOT U!!!!!!!!!!!!!!!
Actually, 9 is A and 10 is C, but other than that, Helper is correct for Connexus!
And @Grace
It's not cheating unless you ask "HEY I NEED THE ANSWERS WHAT ARE THEY?!" because that's obviously cheating. Asking for help on Jiskha isn't cheating, as there are tutors here to help the children learn the stuff.
If you think it's cheating, you aren't told to come on here.
any kid that says this is cheating we don't care we are here because we want to be so lol sorry.
Yes! I 100% agree with you Kacy!

Guys.... don't insult these people who are telling you to stop cheating. Please listen before you send hate comments to me. What if THEY are only CHECKING their answers? You just ADMITTED that you come to cheat. Guys, stop! Other people are just checking their answers; not everyone is bad and cheats like you! What are you gonna do at that STAAR test? Stare into space and pray your friends cheat for you?

Whenever there is replacement, then the events do not affect each other. Or, if the events are unrelated, as with dice and spinners, they are independent.
6: 1/2 * 1/2 = 1/4
7: 1/2 * 3/6 = 1/4
8: 20 total marbles, so
7/20 * 6/20
9: 1/2 * 3/6 (primes are 2,3,5)
10: 3 vowels, 2 P's, 9 total, so
3/9 * 2/9
