Mario and Luigi are throwing Fireballs. Each one throws a fireball twice. Let M1 and M2 represent the distance of Mario's
2 attempts, while L1 and L2 represent the distance of Luigi's 2 attempts. We have that Mi∼Exp(1) while Li∼Exp(2). All attempts are independent of all other attempts. Let M=max{M1,M2} and L=max{L1,L2}. Find P[M>2L].
