WebbA park ranger is searching for bears in a region of the park where on average there are 5 bears per square mile. The bears are solitary independent creatures, so it is reasonable to assume that the numbers of bears in disjoint regions are independent unknowns and that the number expected in any region is proportional to the area of the region. WebbIf your odds of winning are 2 (or 2 wins to 1 loss), that indicates you are twice as likely to win as to lose. On the other hand, if your odds of winning are 0.5 (or 1 win to 2 losses), you’re half as likely to win as to lose. As you can see, the odds of an event occurring is a ratio itself. Therefore, an OR is a ratio of two ratios. naic marchWebbΣ P (X = x₁) = i=1 Let P (X = x) = X 0 1 3 where x = 0, 1,3 P (X = x) Fill up the table and solve the following probabilities. x + 1 7 1.
