Redshirt survival stats
Many moons ago, my bro Dave Devereux and I were involved in writing a Star Fleet security manual for a Star Trek fanclub.

Yes I am aware of just how sad that is, thanks.

One of the things we did was to have an intro chastising James Kirk for the way he went through security officers - the now-infamous "redshirts' - on landing duty.
Now, at last, here are the statistics to show just how bad redshirt life expectancy was.

Q: What factors could increase/decrease the survival rate of red-shirted crewmen?
Besides not getting involved in fights, which usually proved fatal, the crewmen could avoid beaming down to the planet's surface, which is inherent to their end. However, that could result in a court-martial for failure to obey orders.

Besides not beaming down, another factor that showed to increase the survival rate of the red-shirts was the nature of the relationship between the alien life and Captain Kirk. When Captain Kirk meets an alien woman and "makes contact" the survival rate of the red-shirted crewmen increases by 84%. In fact, out of Captain Kirks' 24 "relationships" there were only three instances of red-shirt vaporization.

The caveat to this is when Captain Kirk not only meets the local alien women, but also starts a fight among alien locals. The combination of these events has led to the elimination of 4 crewmembers (3 red-shirts).

Here are the statistics:
Red Shirt Death episodes = 18
Episodes with fights = 55
Probability of a fight breaking out = 70%
Kirk "conquest" episodes = 24
Kirk "conquest" + fights = 16
Kirk "conquest" + red shirt casualty= 4
Red shirt death + fight + Kirk "conquest" = 3
