In most case, you actually can bruteforce all possibilites, and as stochastic models only approximate results, I'd say a computer scientist try to bruteforce and if failed go for other solutions :P

Offender's chance to win on first battle, 47%
Offender's chance to win on second battle having lost the first one, (1-0.47)*0.47=25%
47% + 25% = 72%
Defender chance of winning, that means winning both fight: (1-0.47)*(1-0.47)=28%
72% + 28% = 100%
Nothing lost in outerspace =)
