Consider a country where, to become president, a candidate must win 294 of the total of 578 votes in an electoral college. Let's suppose that the largest region gets 59 votes. Assuming that a candidate wins this region, the number of additional electoral college votes can be approximated by a normal distribution with u = 267.7 and G=47.3 votes. Given that the candidate wins the largest region, what are the chances that he or she becomes the next president? There is a probability that the person becomes president. (Round to three decimal places as needed.)
