In Toastmasters, one of the roles involved is that of Grammarian. One of the main elements of this job is that you need to pick a new word for each meeting to encourage people to improve their vocabulary. Last night the word was ‘Stochastic’.
The meaning of stochastic is: “having a random probability distribution or pattern that may be analysed statistically but may not be predicted precisely.” Another definition is that it means ‘contains random variable’ or ‘involving chance or probability’.
An example sentence would be: “Random, stochastic mutations allow species to diversify.”
