I’m not sure I agree with your numbers under section 1 but the other sections are spot on. Section 2 is particularily good advice. If you need to win 3 ‘deadzones’ to block blitz avenues to lighly defended air assests behind ‘the lines’ you better think carefully about HAVING to win ALL 3.
Perhaps we are looking at things from a different angle for section 1 but I get these odds:
10 infantry vs 6 infantry; probable outcome is 4 attacking infantry (12 IPCs) surviving.
50/50 mark of casualties is 6 Inf, like you state, although a 26% chance the attacker loses. The 50/50 mark means you are equally likely to get better or worse.
5 infantry and 3 tanks vs 6 infantry, probable outcome is 1 attacking infantry and 3 tanks (18 IPCs) surviving.
50/50 mark of casualties is 2 Inf not the 4 Inf you state, in fact, there is a 90% chance the the loses are lower than you state and there is not statistical likelihood of attacker losing or even losing more than a single tank.
5 tanks vs 6 infantry, probable outcome 2-3 tanks (10-15 IPCs) surviving.
The 50/50 mark is 1 tank surviving. In fact, you are nearly going to lose that attack 50% of the time and about 60% you have 1 or less surviving tanks.
