<p>^^^ But the alternative is that pirate 3 and 4 both get one coin. If they make an agreement to split it (it doesn’t have to be 50 -50 but they each get more than pirate 1 was offering them) they would be benefiting. So pirate 3 is safe as long as he goes along with their their agreement and obviously he would want to because he would be getting more than one coin. If they could do this and receive more than one coin why would they go along with pirate 1’s idea?</p>
