Day 152 #314

Good morning! Here's your coding interview problem for today.

This problem was asked by Triplebyte.

You are given n numbers as well as n probabilities that sum up to 1. Write a function to generate one of the numbers with its corresponding probability.

For example, given the numbers [1, 2, 3, 4] and probabilities [0.1, 0.5, 0.2, 0.2], your function should return 1 10% of the time, 2 50% of the time, and 3 and 4 20% of the time.

You can generate random numbers between 0 and 1 uniformly.
