Calculate the total weighted marks obtained by students as per following formula :

Final marks = 25% Term 1 + 25% Term 2 + 50% Term 3

Store the Final marks of students in another Series object.

# Code

import pandas as pd

roll = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

T1 = pd.Series([98, 75, 99, 100, 95, 64, 33, 76, 79, 80], index=roll)

T2 = pd.Series([84, 89, 69, 89, 90, 90, 65, 60, 72, 100], index=roll)

T3 = pd.Series([89, 73, 79, 70, 92, 99, 93, 86, 98, 85], index=roll)

FM = pd.Series(0.25*T1 + 0.25*T2 + 0.5*T3) # Finl Marks series

print(FM)
