help????
Find the experimental probability. Sheila drew single marbles from a bag, recorded the outcome, and replaced the marble. In 50 draws, Sheila drew 20 white marbles and 30 black marbles. What is the experimental probability that the next marble will be black? A.2/5 B.3/5 C.2/3 D.3/7

HI!!
hello can you help me understand this plaese
50 draws, 30 black marbles
the ratio is \(\frac{30}{50}\) which reduces
and no, it is not C
nvm then
and the simplify it
BEWARE of answers with no explanation they are often wrong
*and then
B then
sorry snazzy i like to figure it out
30 divide by 50 equals 0.6 switch that to a fraction is 6/10 and simplify it to 3/5
But that is ur answer :)
thank you :3
No problem :)
And thank u for the medal working on getting human calculator :)
i have 46 medals :D
your welcome
can you help me on 4 more please
sure i will gladly help
Also post a new question if ur are finished with this question
Brahim completed 18 free throws and missed 12. Using experimental probability, how many free throws is he predicted to complete in the next 100 tries? A. 6 B. 36 C. 48 D. 60
i think it is 60
I see ur reason but i will see if u are correct
well first cross out A because if the free throws increases they baskets he makes increases as well
true
i am thinking B for a reason of that 100/18 equals 6 (rounded) but if u do 6*6 since 6 was the number of baskets he made before times it by how many he is doing know i believe it will be 36 :)
ok i will try it and at the end of this quiz i will tell you
Ok
The table shows the results of a spinner with four colored sections. Use the table to answer the question. The spinner is spun 50 more times. Which is the best prediction for the number of times the spinner will stop on white? A. 5 B. 10 C. 25 D. 40
@snazzychazzy
i know i is here
But i am not sure about this since i dont know how many times it was spun the first time :/
I would go with C because you know that their is a big white space on that spinner from the table earlier so you know that white will be the most landed on then any other color :)
sorry @snazzychazzy i had to go eat lunch. You still there??????
yesh
I AM LVL 61 YESH YESH YESH
AWESOME!!!!!!
i feel so amazing right now
lol i bet
i need two more medals D:
so are you for sure its c
lol if i can give you more medals i would
Yes also because you can tell that the white is going to get the most but so will other colors but i wont get so many times to 40 so the other answers would be to low so i think it is C
what i am trying to say is it wont get so low and it wont get to high to the best estimate (also the only answers) would be 25
ok thank you
No problem :)

lol
The table shows the results of drawing letter tiles from a bag. What is the probability that the next tile drawn will have the letter C on it? http://static.k12.com/calms_media/media/1416500_1417000/1416595/1/5ed9dcef8dd7dcfdb451e19005fb94db10bbcd87/FGA_130913_160911.jpg
Is this a fill in da blank or multiple choice??
no i just have to type in the fractions
Ok
a.1/18 b.6/25 c.9/25 d.18/25
C so what your gonna do is take all those numbers and plus them and then take 18/50 and take it and make it a 9/25 :)
and this i am 1000000000000000000000000000000000% sure
ok
\(\Huge\mathbb{Any~More?}\)
A bag contains 45 marbles of various colors. Lena draws 48 times, each time replacing the marble before drawing again. She gets a total of 16 red marbles. Which is best prediction of how many red marbles are in the bag? A. 3 B. 13 C. 15 D. 16
yup
A what i did was took 48 and divided it by 16 to get three
man your awesome
and i got a 60 on my test
Oh no
wait are u on k12??
but which ones did u miss?
#2 #5
last one and second :(
what were the answers??
#2 60
Oh u had that right :(
#5 15
it ok i can take it 2 more times
:)
you ready :D
you probably post a new question
yes
So that way if anyone has different ideas about it they can help too
yup and lets get started

o ooops
a.2/5 b.3/5 c.2/3 d.3/7
WAIT THE ANSWERS ARE THE SAME I THINK LOOK AT THE FIRST QUESTION

yesh they are
o they shoud not be
hold on
ahh they are wooooow that never happen befor
well ok awesome :3
that should be awesome for u
lol i think this next one is different
Three out of 200 machine parts were found to be defective. About how many parts would be expected to be defective out of 2500 parts? A. 15 B. 30 C. 38 D. 67
