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
2. a box contains 6 red balls, 4 yellow balls and 2 green balls. the colours of the balls are mutually exclusive. what is the probability that when a ball is is drawn. a) the ball is redb) either yellow or green
6 red
4 yellow
2 green
a) probability of the red balls
[tex] \frac{6}{12} = \frac{1}{2} [/tex]
b) probability either yellow or green
[tex] \frac{4}{12} + \frac{2}{12} = \frac{6}{12} = \frac{1}{2} [/tex]
3. 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
4. In a bag of red and green sweets, the ratio of red sweets to green sweets is 3:5. If the bag contains 110 green sweets, how many red sweets are there?
Jawaban:
66

9. 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.
Semoga membantu dan bermanfaat :)

10. 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%).

There are severed balls in a bag, two third of them are red colored, on seventh of them are blue. The number of green balls is 6 less than twice the number of blue balls. The number of green balls in the bag is...
=> Dilihat dari kalimat di atas yang di tanyakan adalah jumlah dari bola yang berwarna hijau. Karena dari penjelasan "The number of green balls is 6 less than twice the number of blue balls" yang mana artinya kurang lebih adalah "jumlah bola hijau kurang dari 6 tapi lebih dari 2 jumlah dari bola biru. Jika kurang dari 6 tapi lebih dari 2 angka dari jumlah bola warna biru. So, the answers is..
The number of green balls in the bag is Four (4).

Jawaban:
So, 12 boxes are needed to put all balls with equal number.
Penjelasan dengan langkah-langkah:
GeneralDefinition:
HCF (Highest Common Factor) is the largest number that divides two or more numbers.
Tobeknown:
60 red balls
84 blue balls
72 green balls
Tobeasked:
How many boxes needed to put all balls with equal number ?
Working:
- Write down all prime factors for each numbers.
60 = 2 × 2 × 3 × 5 = 2² × 3 × 5
84 = 2 × 2 × 3 × 7 = 2² × 3 × 7
72 = 2 × 2 × 2 × 3 × 3 = 2³ × 3
- Find the highest common factors by taking the smallest prime numbers.
They are 2² × 3
Conclusion:
Hence, the HCF of 60, 84, and 72 is 2²×3=4×3=12.
