Days Probabilities existed for over forty years and is an important annual event of the French probabilities of school. They help provide an overview of recent research advances in probability (and their applications) in all its trends and give voice to young researchers and PhD students. This meeting is usually held either by the editors of newspaper Probability Seminar at CIRM , or by probability laboratories of provincial universities. The last meeting was held at the CIRM in 2014, and the 2015 was provided by the Toulouse Mathematics Institute (LMI) from 26 to 29 May 2015 . The 2016 edition will be held at the University of Maine at Le Mans.
