Success chance
Build an Embassy and Investigate City always succeed
Plant Spy
[Embassy 50%] [Conscript spy 20%] Regular spy 50% Veteran spy 60% [Elite spy 75%]
If a spy plant fails you will get a flag saying so. You can’t plant a spy when flagged. There is a chance of 1/3 for the flag to disappear each turn. Failing other spy missions does not trigger the flag. You can plant a spy the same turn your spy has been exposed by a failed mission.

Chance of getting away in %:
Immediate Carefully Safely Embassy 40 55 65 Regular spy 60 75 85 Veteran spy 70 85 95
There is an 80% chance of succeeding if not getting caught, thus:
Chance of succeeding in %:
Immediate Carefully Safely Embassy 32 44 52 Regular spy 48 60 68 Veteran spy 56 68 76
Expose Enemy Spy
Same probabilities as above, except you always fail if the enemy does not have a spy.
Initiate Propaganda
You will never get caught
The chance of persuading each citizen is:
spy + government + culture - 5 * units - improvement - capital + nationality
Where:
spy – 10 for veteran spies, 0 for regular
improvement – 20 if the city has courthouse, 0 otherwise (This is not cumulative)
capital – 40 for the capital, 0 otherwise
units – number of units in garrison
nationality – 20 for your own citizen, 0 otherwise.
The government and culture factor are found in the editor.

Democracy is immune against propaganda. But for some reason other governments have a modifier against demo. I have no idea why, but I included it just for fun.

If at least 3/4 of the citizen are persuading, the city will flip. This makes it easier to flip a city of size 4n, than a city of size 4n-1, and in some situation even 4n-2. If the chance of confusing 1 citizen is greater than 1/3, it will be easier to flip a city of size 4 than 2.
If the city does not flip, the persuaded citizen will be confused. Each will give 1 unhappy face. The number of confused citizen are reduced by 1 for each turn. It is not cumulative, if there already are confused citizen in the city, it will be raised to the number of persuaded citizen or stay the same.
The flip chance is not affected by previous propaganda.
