Answer:
Event 3 -> Event 1 -> Event 4 -> Event 2
Step-by-step explanation:
The probability of choosing a certain pen is the number of that pen in the box over the total number of pens in the box.
So we have that:
Event 1: We have 4 black pen and 20 total pens, so P = 4 / 20 = 1 / 5
Event 2: All pens are black or orange so the probability is 1.
Event 3: We don't have white pens, so the probability is 0.
Event 4: We have 2 black pen and 5 total pens, so P = 2 / 5
Listing from least likely to most likely, we have:
Event 3 -> Event 1 -> Event 4 -> Event 2
Answer:
x=0

Answer:
Option B
27x³ – 108x² + 144x – 64
Step-by-step explanation:
(3x – 4)³
(3x – 4) × (3x – 4) × (3x – 4)
(9x² – 12x – 12x + 16) × (3x – 4)
(9x² – 24x + 16) × (3x – 4)
27x³ – 36x² – 72x² + 96x + 48x – 64
27x³ – 108x² + 144x – 64
Thus, The answer is 27x³ – 108x² + 144x – 64
