1. A bag of ball contains 12 balls: 3 black, 8 yellow, 1 purple. 5 balls are drawn randomly without replacement. what is the probability that exactly 3 yellow balls are drawn
Peluang terambil 3 bola kuning adalah 0,0364.
Penjelasan dengan langkah-langkah:
Peluang merupakan bilangan yang menyatakan kemungkinan terjadinya suatu peristiwa atau kejadian. Rumus yang digunakan untuk menghitung peluang, yaitu:
P(A) = [tex]\frac{n(A)}{n(S)}[/tex]
Dengan:
P(A) adalah peluang kejadian An(A) adalah banyaknya kejadian An(S) adalah banyaknya seluruh kejadianDiketahui:
Sebuah kantong terdiri dari 12 bola, 3 bola diantaranya berwarna hitam, 8 berwarna kuning, dan 1 bola berwarna ungu.
Ditanya:
Jika diambil 5 bola tanpa pengembalian, berapa peluang terambilnya 3 bola kuning?
Jawab:
Peluang terambilnya bola kuning ada 2 kemungkinan, yaitu:
3 bola kuning, 2 bola hitam3 bola kuning, 1 bola ungu, 1 bola hitamPeluang 3 bola kuning, 2 bola hitam:
P(A) = [tex]\frac{3}{12}.\frac{2}{12}[/tex]
P(A) = [tex]\frac{5}{144}[/tex] = 0,0347
Peluang 3 bola kuning, 1 bola hitam, 1 bola ungu:
P(A) = [tex]\frac{3}{12}.\frac{1}{12}.\frac{1}{12}[/tex]
P(A) = [tex]0,0017[/tex]
Maka peluang terambil bola kuning = 0,0347+0,0017 = 0,0364

2. a bag contains 6 blue balls, 5 green balls and 3 red balls. three balls are selected random. a) find the probability that at least one red ball is selectedb) find the probability that at least one green ball is selected
Jawaban
n(b) = 6 buah
n(g) = 5 buah
n(r) = 3 buah
n(S) = 14
a. P(r) = [tex]\frac{n(r)}{n(S)}[/tex]
= [tex]\frac{6}{14}[/tex]
= [tex]\frac{3}{7}[/tex] atau 0,43
b. P(g) = [tex]\frac{n(g)}{n(S)}[/tex]
= [tex]\frac{5}{14}[/tex] atau 0,36
3. Sasha has a bag with · 5 black balls, · 3 white balls, and · 4 red balls. If she takes a ball out of the bag without looking, what are her chances of getting a white ball? A. 1 chance out of 3 B. 3 chances out of 9 C. 3 chances out of 12 D. 9 chances out of 12
Chapter : Chance
Math : 9th grade
sum of balls = 5 + 3 + 4 = 12 balls
a chance of white ball = 3/12
Answer : C
n(A) = 3
n(S) = 5 + 3 + 4 = 12
P = n(A) / n(S)
P = 3/12
3 chances out of 12 ( C )
4. there are 5 white balls,8 red balls,7 yellow balls and 4 green balls in a container.a ball is randomly drawn.the probability of selecting either a red or a white ball is
(5 + 8 + 7 + 4)= 24
RED balls = 8/24
=1/3
White balls = 5/24Total amount of balls=5+8+7+4=24
RED/WHITE
Red+White = 13
13/24

6. 1. Dua uang logam serupa di lambungkan serentak. Berapakah peluang tidak muncul hasil yang sama pada kedua uang logam? a. 1 b. 3/4 c. 1/2 d. 1/4 e. 1/16 2. A box contains 3 red balls, 4 white balls, 2 blu balls and 3 yellow balls. Two balls are randomly drawn without replacement. The probability of selecting a white ball in the first draw and a yellow ball in the second draw is ...... a. 1/11 b. 2/11 c. 4/11 d. 4/12 e. 6/12
Nomor 1.
Dua uang logam dengan sampel = {(A,A),(A,G),(G,A),(G,G)} menandakan ada 4 ruang sampel.
Dengan tidak menunjukkan hasil yang sama, yakni : {(A,G),(G,A)}, terdapat 2 sampel kejadian, sehingga:
n(S) = 4
n(A) = 2
Yang menyebabkan:
P = n(A) / n(S)
P = 2/4
P = 1/2 [C]
Nomor 2.
Pengambilan pertama : Bola putih
Ada 4 bola putih dari 12 bola seluruhnya, sehingga:
P1 = 4/12 = 1/3
Pengambilan kedua : Bola kuning
Ada 3 bola kuning dari 11 bola seluruhnya (karena 1 sudah diambil tanpa pengembalian), sehingga:
P2 = 3/11
Karena kejadian bersyarat.
P = P1 x P2
P = 1/3 x 3/11
P = 1/11 [A]

9. A bag contains 3 blue balls, 7 red balls and 1 green ball. Joe takes out one ball at random and then puts it back. If he does this 66 times, how many times would he be expected take out: (a) a blue ball (b) a ball that is not blue (c) a yellow ball
Penjelasan dengan langkah-langkah:
S = {5 red balls + 4 green balls + 3 blue balls}
N(S) = (12)
Event A = Choosing a Red Ball
A = {5 red balls}
N(A) = (5)
P(A) = n(A)/n(S) = 5/12
Event B = To choose a Blue Ball
B = {3 blue balls}
N(B) = 3
P(B) = n(B)/n(S) = 3/12 = 1/4
Therefore probability of choosing a red ball is 5/12 (42%) , and that of blue balls 1/4 (25%).
Artinya:
S = {5 bola merah + 4 bola hijau + 3 bola biru}
N (S) = (12)
Event A = Memilih Bola Merah
A = {5 bola merah}
N (A) = (5)
P (A) = n (A) / n (S) = 5/12
Peristiwa B = Memilih Bola Biru
B = {3 bola biru}
N (B) = 3
P (B) = n (B) / n (S) = 3/12 = 1/4
Oleh karena itu, kemungkinan memilih bola merah adalah 5/12 (42%), dan bola biru 1/4 (25%).

10. A bag contains 8 red and 10 blue marbles a marble is drawn at random what is the probability of drawing a red marbles
Jawab:
The probability of drawing a red marble is [tex]\frac{4}{9}[/tex]
Penjelasan dengan langkah-langkah:
The bag contains 8 red marbles and 10 blue marbles. So, there are 18 marbles in total inside the bag.
Since there are 8 red marbles and there are 18 marbles in total, the probability of taking a red marble is:
P(red) = [tex]\frac{number \:of\; red}{number\:in\: total} = \frac{8}{18} = \frac{4}{9}[/tex]
Hence, the probability of drawing a red marble is [tex]\frac{4}{9}[/tex]
11. Mrs Kim buys 60 balls for $700. There are red balls and white balls. Red balls cost $11 each and white balls cost $13 each. How many balls of each colour has she bought?
Jawab:
x=11
y=13
ax + by=700
a + b=60
11a + 13b=700
11a=700 - 13b
a=700/11 - 13/11b
700/11 - 13/11b + b=60
700/11 - 2/11b=60
700 - 2b=660
-2b=660 - 700
=-40
b=20
11a + 13(20)=700
11a + 260=700
11a=700 - 260
=440
a=40
So, Mrs Kim bought 40 red balls and 20 white balls.
