Jacopo Riccati was an Italian mathematician who wrote on philosophy, physics and differential equations. He is chiefly known for the Riccati differential equation.

Giovanni Rizzetti was a friend of Riccati who wrote on probability. We have one paper cited by Todhunter: Ludorum Scientia, sive Artis conjectandi elementa ad alias applicata. It may be found on pages 215-229 and 295-307 of Actorum Eruditorum... Supplementa. Tomus IX, Lipsiae. It is reprinted in Opuscula omnia Actis eruditorum Lipsiensibus, Tomus 7 (1730-1740) on pages 48-60 and 76-86 to which the link above refers.

For which see the paper by Belcastro "Considerazioni di Giovanni Rizzetti sul calcolo delle probabilità e sul teorema di Jakob Bernoulli," Historia Mathematica 21 (1994) pp. 420-454.
