okay. Simple for anyone to find the probability that's around. Lisa, Select the Union Soldier is from the X I court for looking at our table. We have excite courts. We have 9188 that our strength and three eight year one that are lost. And then we're gonna some Those two told us together that's 114753 That's equal to 91 it beats plus 3 81 divided by our total. So we yet general points beloved three for Part B. We want to find the probability that a soldier was lost in battle. Okay, so our Children number of bosses is 20 to 803 over a total number of strength on lost inserts 2 to 8. You agree? Plus our total number of upstream. Yes, equal deal, but see about it by two You three waas 91950 for that 0.199 Comport See, we want to find the probability that's an eye courts soldier was lost in battle. Do we see that we have a corpse? We have 6000 059 were lost over our total losses, which is 2 to 8 girls. Three. So that's equal to the following. That is 0.266 party we want which group had the highest? Probably not be lost in battle. Well, looking at our strength losses, we see that the one with the highest strength and the lowest lost is our be our corpse. Report E where us? Which group has the highest probability of loss. So we want the maximum loss in the middle of strength. So that is our high courts.
