A school has a population of 206 workers, of which 62 are French-speakers, 36 are Russian-speakers, and 91 are English-speakers. 12 workers speak both French and Russian, 21 speak Russia and English, 41 speaks English and French, and 8 speak all the languages. Develop a Venn diagram to illustrate the data, hence use it to find the probability that a worker picked at random: (1) Does not speaker English, (2) Speak neither of the languages, (3) Speak French and Russian but not English.
