Show all steps. Leave your final answers in fraction form unless otherwise stated. Determine the odds against the event occurring. 1. The probability of an event occurring is Use the following information to answer the next two questions. A survey of high students was used to estimate the percentage of students who participate in school and non-school extra-curricular activities, as well as the percentage who do not participate in any extra- curricular activities. The results of the survey are shown in the Venn diagram below. Participation in School and Non-School Extra-Curricular Activities School Non - School 38% 26% 21% 2. Determine the odds in favour of randomly selecting a high school student who participates in school extra-curricular activities. 3. Are the participation in school extra-curricular activities and the participation in non-school extra- curricular activities mutually exclusive events? Justify your answer. 4. A game has three possible outcomes: X, Y, or Z. If P(X) = 0.6 and P(Y) = 0.3, what is the probability of event Z? 15% Re
