Set the action probabilities at chance information set infoset.

Parameters:

• probs (array-like) – The action probabilities to set

Raises:

• MismatchError – If infoset is not an information set in this game

• UndefinedOperationError – If infoset is not an information set of the chance player

• IndexError – If the length of probs is not the same as the number of actions at the information set

• ValueError – If any of the elements of probs are not interpretable as numbers, or the values of probs are not non-negative numbers that sum to exactly one.
