There are 15 marbles at first, 5 are red. after you pick one red marble, there are 4 reds left in a bag of 14 marbles The two events are dependent so you have to multiply them. = $\frac{ 5 }{ 15 } * \frac{ 4 }{ 14 }$

ty Here are a few more

@horsegal244 okay

8. horsegal244

You dont need to keep tagging me but ty

9. horsegal244

I think its the second one

okay, sorry. ;n; so you have a 22/50 chance of getting tails and A 20/50 chance of getting a blue marble, the chance of both happening at the same time is 22/50 * 20/50 = 440/2500

so yeah, the second one. c:

Yay i was right Lol!

anything else? ;u;

14. horsegal244

if she replaces the chip then the probability will remain the same, so it is 5/25 * 5/25 = 25/625 because the events are still dependent.

16. horsegal244

Is this correct?

yes that is correct. c:

18. horsegal244

there are 36 possibilities. only 2 of those possibilities will give you a total of 11 so you have 2/36 =

ignore the equal sign at the end, the answer is 2/36

21. horsegal244

18?

1/18 if you want ti simplify

23. horsegal244

Ok

unfortunately I need to be off now. :c good luck with your studies. <3

25. horsegal244

I have 2 more questions...

26. horsegal244

I really can't i'm sorry, it's way late over here. They're both probability right?

just use the methods I showed you in my solutions, it's the same question with different values.

29. horsegal244

Huh ok...
