Problem 2356. Simulating the selection of a state with given probabilities

Created by Omer

Solve Later

Lets say we have 3 different states [1,2,3] with the probabilities of occurrences of each state is given as [0.5 0.2 0.3]. Which means 50% state 1 will be selected among others. Generate randomly selected states with the probabilities given

Output array will be consisting of state numbers based on the probabilities given as input.

Example: (Quick tip: The higher simulation sampling sizes the more robust results)

It's not clear to me what select_state is supposed to return. I would have thought it was one of the state (i.e. one of 1, 2, 3, ...) but it's not what the test suite tests for.
Returning the passed in probability with a very small deviation is enough to pass the test suit. This doesn't seem right.

Guillaume, i changed the problem output to states rather than the probability values. This way looks better i presume. Thanks for the comment. Cheers
