Missing Part:
a. A red ball is drawn
b. A white ball is drawn
Answer:
a.
b. 
Step-by-step explanation:
Given



First, we need to calculate the total



Solving (a): Probability of Red.
This is calculated by dividing number of red balls by the total
So:



Solving (a): Probability of White.
This is calculated by dividing number of white balls by the total
So:



C = R - p
add C to both sides
R = C + p
subtract p from both sides
R - p = C ⇒ C = R - p
Answer:
The answer is A
Step-by-step explanation:
2x + 3 /12 = 2x/8
⇒ 48x/24 + 6/24 = 6x/24
⇒ (48x+ 6)/24= 6x/24
⇒ 48x+ 6 = 6x
⇒ 48x- 6x= -6
⇒ 42x= -6
⇒ x= -6/42
⇒ x= -1/7
