John Venn, FRS, [2] [3] FSA [4] (4 August 1834 – 4 April 1923) was an English mathematician, logician and philosopher noted for introducing Venn diagrams, which are used in logic, set theory, probability, statistics, and computer science.
A Venn diagram is a widely used diagram style that shows the logical relation between sets, popularized by John Venn (1834–1923) in the 1880s. The diagrams are used to teach elementary set theory, and to illustrate simple set relationships in probability, logic, statistics, linguistics and computer science. A Venn diagram uses simple closed ...
Dr John Venn, who died in 1923 aged 88, created the device in the early 1900s, as well as giving his name to Venn diagrams.
John Venn, who provided a thorough exposition of frequentist probability in his book, The Logic of Chance [1]. Frequentist probability or frequentism is an interpretation of probability; it defines an event's probability as the limit of its relative frequency in infinitely many trials (the long-run probability).

The principal examples of such machines are those of William Stanley Jevons (logic piano), [1] [2] John Venn, [3] and Allan Marquand. [4] [5] Contemporary logical machines are computer-based electronic programs that perform proof assistance with theorems in mathematical logic.
The frequency theory approach to probability was first developed by Robert Ellis and John Venn late in the 19th century. The Fortune Teller by Vouet , 1617 While the mathematical elite was making progress in understanding randomness from the 17th to the 19th century, the public at large continued to rely on practices such as fortune telling in ...
