Answer 1

1:A(correct)
2:A (correct)
3:B (incorrect) complement is all the outcomes that are not the given outcome
4:B (correct)
5:technically isn't that 0? the odds of a spinner landing on red on a board comprising of only blue green and yellow is 0 (its impossible)
assuming that there should be red on the board: D (incorrect) there are 4 (random)outcomes, the odds of any one are 1:3.

Answer 2

question 5 confuses me. the question on my quiz is what are the odds AGAINST the spinner landing on red. wouldn't it be 3:4?
