“How can you find the probability of three or fewer earthquakes in both cities combined?”
Scott’s brow furrowed. “I can find the probability of three earthquakes in Tokyo and zero in San Francisco, or two in Tokyo and one or zero in San Fran-“
“There’s an easier way,” I chided him.
He thought for a moment before sudden realization spread across his face. “Oh! They’re independent! So I only need to use one Poisson distribution, whose mean is the sum of the other two means!”

I buried my head against his shoulder for just an instant before reluctantly pulling away. “You’re so smart! You’re really catching on quickly. I’m surprised you even need a tutor. I thought you aced all your classes.”
“I usually do. I don’t know what it is about stats. It just doesn’t click for me.”
“It will! And until then, I’ll tutor you as much as you need it. Until you’re getting an A+!”
