A Random Variable $X$¶

Our probability distribution of $X$, shown as a table:

In [2]:
# Our random variable X
dist_df = pd.DataFrame({"x": [3, 4, 6, 8],
                        "P(X = x)": [0.1, 0.2, 0.4, 0.3]})
dist_df
Out[2]:
x P(X = x)
0 3 0.1
1 4 0.2
2 6 0.4
3 8 0.3
In [3]:
fig = px.bar(dist_df, x="x", y="P(X = x)", title="Distribution of X")
# fig.write_image("distX.png", "png",scale=2)
