Step-by-step explanation:
Number of balls in the urn = 12
Number of white balls in the urn = 4
So, number of balls which are not white = 12 - 4 = 8
We know that probability = No. of outcomes/Total number of outcomes
Let
denotes the event of getting white ball by A, B and C
a) each ball is replaced after being drawn.
Probability = Number of white balls/Total number of balls
Solution: ![P(A_i)=P(B_i)=P(C_i)=\frac{4}{12}=\frac{1}{3}](https://tex.z-dn.net/?f=P%28A_i%29%3DP%28B_i%29%3DP%28C_i%29%3D%5Cfrac%7B4%7D%7B12%7D%3D%5Cfrac%7B1%7D%7B3%7D)
b)the balls that are withdrawn are not replaced.
Solution:
If A wins: ![P(A_1)=\frac{4}{12}=\frac{1}{3}](https://tex.z-dn.net/?f=P%28A_1%29%3D%5Cfrac%7B4%7D%7B12%7D%3D%5Cfrac%7B1%7D%7B3%7D)
If A lost and B wins: ![P\left ( B_1|A_1^{c} \right )=\frac{4}{11}](https://tex.z-dn.net/?f=P%5Cleft%20%28%20B_1%7CA_1%5E%7Bc%7D%20%5Cright%20%29%3D%5Cfrac%7B4%7D%7B11%7D)
If A and B lost and C wins: ![P\left ( C_1|A_1^{c}\,B_1^{c} \right )=\frac{4}{10}](https://tex.z-dn.net/?f=P%5Cleft%20%28%20C_1%7CA_1%5E%7Bc%7D%5C%2CB_1%5E%7Bc%7D%20%5Cright%20%29%3D%5Cfrac%7B4%7D%7B10%7D)

Answer:
The cost of the bench is <u>425 dollars</u>.
Step-by-step explanation:
<u>Let x represent the garden table.</u>
<u>Let y represent the bench.</u>
x + y = 804
x = y - 46
<u>Use the substitution method.</u>
y - 46 + y = 804
2y - 46 = 804
<u>Add 46 to both sides.</u>
2y = 850
<u>Divide both sides by 2.</u>
y = 425
Answer:
The cost of the bench is 425 dollars.
