Step 1. Given Information: Two official languages in Canada are English and French. When a Canadian is chosen randomly and asked about their mother tongue, the distribution of responses, combining the majority of separate languages from the broad Asia/Pacific region is as follows: - Probability of English is P(E) = 0.63 = - Probability of French is P(F) = 0.22 - Probability of Other languages from Asia/Pacific region is P(A/P) = 0.06 Step 2. Probability Distribution: In a probability distribution: - The probabilities must be non-negative - The sum of probabilities of all events should add up to 1. Using the second condition, we can calculate the probability of Other languages from Asia-Pacific region as: P(Other) = - 1 (P(E) + P(F) + P(/p)) = - 1 0.91 = 0.09 Therefore, the probability that should replace "?" is 0.09. Step 3. Probability of not English: The probability that a Canadian's mother tongue is not English can be calculated by using the complementary probability formula: P(not English) = 1 - P(English) = 1 0.63 = 0.37. Therefore, the probability that a Canadian's mother tongue is not English is 0.37. Step 4. Probability of Other languages: The probability that a Canadian's mother tongue is a language other than English or French can be calculated by adding the probabilities of Other languages from Asia/Pacific region and languages other than Official Languages i.e., P(Asian/Pacificor Other) = P(Asian/Pacific) + P(Other) = 0.06 + 0.09 = 0.15. Therefore, the probability that a Canadian's mother tongue is a language other than English or French is 0.15
