PLEASE HELP ME! THIS IS MY LIFE! I WILL GIVE U A MEDAL!
Henry grabs one shoe at a time at random without replacement from a box of fourteen shoes in his closet. The box contains 6 brown shoes, 4 black shoes, and 4 sneakers. What is the probability that the first two shoes he chooses will be brown? Round to the nearest percent if necessary. six percent seven percent sixteen percent eighteen percent
I am in between 6% 7% and 16%
I don't know which one to pick?
the P that he will choose brown at the first time is, (6 / [6+4+4] ) which equals, 6/14 and simplifies to 3/7 the P that he will choose brown at the first time is, (5 / [5+4+4] ) which equals, 5/13 The probability of 2 event happening at once is the product of the 2 probabilities.
So.....
If you have any questions about what I wrote, I will be happy to explain :)
So which one would it be?
product of 2 probabilities is when you multiply the 2 probabilities, (6/14) times (5/13)
Ok Wait Let Me Solve That
find the fraction and put it (approximately) in terms of percent go ahead.....
0.16483516483
@SolomonZelman I solved it :)
But know what is the answer?
So the answer is 16% right?
???????? Is it 16%?
yes, you are indeed correct!
YAY! THANKS!
You welcome !
Thank you so much can u help me with another question?
@SolomonZelman can you help me with another one?
Yes, I can try at least :)
Ok thanks :)
@SolomonZelman please come help! :)
@SolomonZelman & @sleepyjess can you please come help... Thank you :)
okay, can you calculate the number of people in the class first ?
What do you mean?
@SolomonZelman help i don't get it!
How many people sold between 0 and 9 ? How many people sold between 10 and 19 ? How many people sold between 20 and 29 ? How many people sold between 30 and 39 ? How many people sold between 40 and 49 ? answer each question for me please.
so i have to subtract?
@SolomonZelman do i have to subtract?
Subtract what ? just answer each of the 5 questions I have posted at first.
??
ohhh
i get it
1) How many people sold between 0 and 9 ? 2) How many people sold between 10 and 19 ? 3) How many people sold between 20 and 29 ? 4) How many people sold between 30 and 39 ? 5) How many people sold between 40 and 49 ? answer each question for me please.
0-9= 2
10-19 = 5
20-29= 8
30-39= 3
40-49 =4
ok i finish!
yes, correct.
:)
So how many people are there in the entire class ?
22 :)
yes.
....
how many people in the class sold less than 20 hoagies ?
i don't get it :( sorry
how many people sold btw 0-9? and how many people sold btw 10-19? 2 and 5 both of these, btw 0-9 and btw 10-19 sold LESS THAN 20, So, 7 people in the class sold less than 20 hoagies.
0-9
so 20 would be the answer for the first one?
Well, A) asks for the percent of the people in class that sold less than 20. You know that 7 people in class (out of the 22 people class) sold less than 20. So 7/20 would be the fraction and percent wise, 35. Looks like B is the closest, even though still far from the truth.
B?
yes for the first row second column, it is B.
I mean to fill in B into 1st row , 1st column
Ok
Okw aht about the second one
lets do the question that asks what is the greatest number of hoagies that could have been sold by 1 student. What do you think, which one is it ?
ok um...
49
Yes, you are correct !
are u sure?
just cuz it;s the big number?
yes, I am sure ! Now, do the question that says "what is the total number of students in the class which one do you think is it ?
so the second column is d
first column, B second column D is what we got so far. can you do the third column ?
22!
Yes, so first column, B second column D third column, C I don't think you need me for the forth column.
YAY! :)|dw:1399423846642:dw|
