Instructions:

Simulate 100,000 draws from the Poisson(1) distribution, saving them as X.

Simulate 100,000 draws separately from the Poisson(2) distribution, and save them as Y.

Add X and Y together to create a variable Z.

We expect Z to follow a Poisson(3) distribution. Use the compare_histograms function to compare Z to 100,000 draws from a Poisson(3) distribution.

# Simulate 100,000 draws from Poisson(1)

# Simulate 100,000 draws from Poisson(2)

# Add X and Y together to create Z

# Use compare_histograms to compare Z to the Poisson(3)
