Question

if a bag has 40 red and blue marbles and a quarter of them are red,what is the probability of picking a blue marble?

Answer 1

Well 25% of the 40 marbles are red, and 25% of 40 is 10. 40-10=30, which means there are 30 marbles. That means the probability is 30/40, which when simplified is 3/4.

Answer 2

ahh thank you!i kept trying to do 60/40 for some reason

Answer 3

Oh okay yeah no prob. :)

Answer 4

and the fraction 3/5 cant be reduced correct?

Answer 5

Nope, nothing goes into 3 & 5 both besides 1.

Answer 6

thought so:)thank you very much for your help.

Answer 7

No problem :) If you need any other help I'll try my best to help :)

Answer 8

now i have a question like the marble one again but its three-quarters of them are red and it wants to know the probability of picking a blue marble

Answer 9

are there 40 total?

Answer 10

there are 40 marbles still.

Answer 11

40 red and blue.

Answer 12

K since we know a quarter of 40 is 10, that means 3 quarters is 30. There are 30 red and only 10 blue this time. That means probability is 10/40, but when simplified is 1/4.

Answer 13

what about the probability of picking a vowel from the word total?

Answer 14

it should be 2/6 correct?

Answer 15

K I'm gonna give you hints on this one and see if you can figure out.
Hint: There are 5 letters in 'total', but only 2 vowels.

Answer 16

i meant 2/5

Answer 17

Yep :)

Answer 18

okayy ready for a hard question?

Answer 19

Lol I'll try my best to solve it :)

Answer 20

im sure you can you seem pretty smart:)

a deck of cards is made up of 4 suits:clubs,diamonds,hearts,and spades.each suit has 13 cardds with this range:2,3,4,5,6,7,8,9,10,J,Q,K,and A.
what is the probability of drawing a 7 or 8 from the deck of playing cards?

Answer 21

Okay so we see, there are 4 7's and 4 8's. This gives us 8/52. We can divide both by 2 to simplify it to 4/26. We can divide by 2 again, and get 2/13 as our probability.

Answer 22

i could get the 52 i just didnt know how many 7's and 8's.and thanks for helping i need to pass this quiz to pass my class its my last quiz and i graduate!

Answer 23

Omg I wish you best of luck :)

Answer 24

and it's Algebra I right?

Answer 25

it says its algebra 2 but i think it seems more like algebra 1

Answer 26

if you are trying to calculate the probability of rolling an even number on each die when rolling two dice,how large is the sample space?
i keep getting 9 idk if thats right

Answer 27

Oh okay. I'm doing Algebra II virtual right now.

Answer 28

im good with all of my other online classes its just hard with math because it doesn't show me what i did wrong in the problem.

Answer 29

Idk what the sample space is so gonna figure out what that is quickly to try to help :)

Answer 30

im trying to google it:)

Answer 31

The sample space of an experiment is the set of all possible outcomes of that experiment.

Answer 32

Yuck.
Die #1, Die #2
2,2
2,4
2,6
4,4
6,6
I would think there's only 5. Cause if you do 4,2 that's already on there and yeah.

Answer 33

this might help my choices for answers are
A.6
B.12
C.36
D.18

Answer 34

Oh okay um..oh yeah forgot one.

6,6
4,6
There's 6 possibilities, A

my next question is in a class of all girls,24 of the 30 have brown hair.what is the probability of randomly picking a girl with brown hair?
dont i just do 24/30?

Answer 36

Yeah you just simplify if needed. and when you simplify you get 4/5.

Answer 37

i think i got this one wrong last time im so blonde.
what is the probability of picking a consonant from A to Z?

Answer 38

Lol. Well there's 21 consonants, and 5 vowels. Your probability would be 21/26

Answer 39

Answer 40

which is more likely event, rolling a 4 on a die or a 5?

Answer 41

Both are the same :) They both got probability of 1/6.

Answer 45

my choices for answers are
A.13
B.26
C.52
D.5

Answer 46

I don't really know.

Answer 47

ill just guess:)

Answer 48
