Problems teaching probability in Tonga (in the South Pacific) led to the question how language and culture affect the understanding of probability and uncertainty. The research uses a discursive approach to find the endorsed narratives which underlie Tongans' reasoning in situations of uncertainty. I aim to justify the claim that the Tongan Language and the Tongan way of life interact to make the concept of uncertainty unimportant and the concept of probability almost redundant in day to day discourse.
