Homework Equations
The Attempt at a Solution
I fixed A in the first place with probability P. Then I made cases of no one dying, one dying, and so on till all dying, which got me : P x ( 4C0P0(1-P)4 + 4C1P1(1-P)3 + 4C2P2(1-P)2+ 4C3P3(1-P)1+ 4C4P4(1-P)0 ) which got me P as the answer, which was wrong.
