Answer:
x = -52
Step-by-step explanation:
1/3x-2/3=-18
Multiply each side by 3 to clear the fractions
3(1/3x-2/3)=-18*3
x - 2 = -54
Add 2 to each side
x-2+2 = -54+2
x = -52

Assuming that the balls are not replaced;

= 5/42
(the numbers are decreasing in the denominator as you are presumably taking out the red balls. In the denominator, there is one less ball each time since you took out a red one).
Therefore, the probability of selected 4 red balls consecutively without replacement is 5/42.
