If any given TNT yeeter can yeet a TNT accurately 75% of the time and 25% of the time it explodes in the TNT yeeter's hand. Would it be wise for a TNT yeeter to yeet a TNT at a group of 7 enemies effectively killing them all. But if it explodes in the TNT yeeter's hand 9 TNT yeeters will have a 50% chance to die and a 50% chance to live. Not including the TNT yeeter yeeting the TNT.
