Question 17 (1 point) Teagan is planning her university schedule. She is trying to decide between four different mathematics courses. She has been told, based on the results from previous years, that . Course 1: the odds against getting an A are 9:2 . Course 2: the odds in favour of getting an A are 3:11 . Course 3: the probability of getting an A is 19 4 . Course 4: the probability of not getting an A is 0.78 Teagan wants to get as high a mark as possible. The course she should take is Course AQuestion 18 (1 point) The probability of rolling a 4 on a die and getting heads on the flip of a coin is 12 The probability of getting heads on the flip of a coin is 0.5. Find the probability, to the nearest hundredth, of rolling a 4 on a die.A drawing of bag contains 5 white, 3 black, and 3 patterned marbles, as shown below. The odds in favour of randomly pulling a black marble from the bag are 3:8. A new drawing of the bag of marbles is being created. The patterned marbles in the bag above will be coloured in to create black marbles, the number of black marbles would have twice as many in the new drawing and the number of white marbles will stay the same. The odds in favour of pulling a black marble in the new drawing are Record your answer in the form a:b
