Answer:
-2
Step-by-step explanation:
Each term is being multiplied by -2.
9(-2) → -18
-18(-2) → 36
Assuming the coin is fair, probability of getting one tail is 50%, probability of getting two tails in a row is 50%*50% = 25% or 1/4
Answer:
45
Step-by-step explanation:
20 / 9 = 2.222222222223
100 / 45 = 2.222222222223
9 is 45% of 20 and 45 is 45% of 100.

The answer is 171!
