Given a vector of frequencies c = (C₁, C2, ..., Cn), where n ≥ 1 and all c, are non-negative integers. We can convert this vector into a probability vector p = (P1, P2,..., Pn) using the formulation: P₁ = = ci/(Σ!=1 ci), for all i. Write a function freq_to_prob (c) that takes a frequency vector c as input and returns the corresponding probability vector p.

Write program in python 

Given a vector of frequencies c = (C₁, C2, ..., Cn), where n ≥ 1 and all c, are non-negative integers. We can
convert this vector into a probability vector p = (P1, P2,..., Pn) using the formulation: Pi = C₁/(-1 Ci),
for all i. Write a function freq_to_prob (c) that takes a frequency vector c as input and returns the
corresponding probability vector p.
