Game theory: Pirates game

From Wikipedia (don’t look unless you want the answer):
There are five rational pirates, A, B, C, D and E. They find 100 gold coins. They must decide how to distribute them.
The Pirates have a strict order of seniority: A is superior to B, who is superior to C, who is superior to D, who is superior to E.
The Pirate world’s rules of distribution are thus: that the most senior pirate should propose a distribution of coins. The pirates should then vote on whether to accept this distribution; the proposer is able to vote, and has the casting vote in the event of a tie. If the proposed allocation is approved by vote, it happens. If not, the proposer is thrown overboard from the pirate ship and dies, and the next most senior pirate makes a new proposal to begin the system again.
Pirates base their decisions on three factors. First of all, each pirate wants to survive. Secondly, each pirate wants to maximize the amount of gold coins they receive. Thirdly, each pirate would prefer to throw another overboard, if all other results would otherwise be equal.

Suppose you’re on a game show. There are 3 doors, behind one is a car and behind the other two are goats. The host knows where the car is. You select a door (#1) and the host opens another (#2), they tell you that there are goats behind that door (goats in #2). They also tell you that you can stay with your original guess (#1) or select the other door (#3).
Do you have a higher probability of winning depending on keeping Door #1 or by switching to Door #3?
