hypothetical triathlon competition includes three sequential activities: running, cycling, and swimming. Each participant attempts to break the fastest time achieved in previous competitions, currently set at T = 2 hr. The times for completing the three activities for this specific participant are exponentially distributed with mean 12 min for running, 1.1 hr. for cycling, and .7 hr. for swimming; that is,

Develop Excel model to estimate the chances of a specific participant beating the current record based on six simulation runs and 10 trials per run.
