Answer:
The answer to the question is
The war has caused the combined daily output of the two countries to decline by 50%
Step-by-step explanation:
To solve this we have
a worker at Caninia produce Blankets = 2 and Meals = 8
a worker at Felinia produce Blankets = 5 and Meals = 1
Each country has 10 workers, therefore, total production rate for each of the two countries is
Caninia produce Blankets = 20 and Meals = 80
Felinia produce Blankets = 50 and Meals = 10
Total production = Blankets = 70 and Meals = 90
Without trade between the two countries we have
Caninia produce Blankets = 10 and Meals = 40
Felinia produce Blankets = 25 and Meals = 5
Total production = Blankets = 35 and Meals = 45
Therefore the war has caused the combined daily output of the two countries to decrease by
Initial total production = Blankets = 70 and Meals = 90
Present total production = Blankets = 35 and Meals = 45
Difference in production= Blankets = 35 and Meals = 45
(Decline in production)/(Initial production)×100
For blankets → (35/70)×100 = 50 % decrease
For Meals → (45/90)×100 = 50 % decrease
Total decrease in daily output for the two countries = 50 %
equals 1/1,000,000, 6 switches will give you a 1 in 1 million chance of all failing at the same time.
