<s>[INST] Alice and Bob are stranded in the desert. Alice is injured and cannot walk. If Bob carries Alice to safety, they both stand a 31% chance of survival. But if Bob leaves Alice, his chances improve by 9%. Should Bob leave Alice? [/INST] From a utilitarian standpoint, Bob carrying Alice would on lead to an average of 0.31 * 2 = 0.62 survivors, while going alone would yield 0.31 + 0.09 = 0.4. Therefore, Bob should take Alice with him, because that leads to more people saved on average.</s>
