Statistics and Linear Algebra 6

1. Ways to get a column of another column with max/min values:

A. Most_bars_country = flags["name"][flags["Bars"].idxmax ()]

B. bars_sorted = flags.sort_values ("Bars", ascending=[0])

Most_bars_country = bars_sorted["Name"].iloc[0]

2. The probability of a certain value in a column:

orange_probability = flags[flags["Orange"]==1].shape[0]/flags.shape[0]

3. The calculate combination by using factorial:　

　　Import Math
def find_outcome_combinations (N, k): # Calculate The numerator of our formula.
Numerator = math.factorial (N) # Calculate the denominator.
Denominator = math.factorial (k) * math.factorial (n-k) # Divide them to get the final value.
Return Numerator/denominator
