C) The complement is landing on "Go Forward 2 spaces," and the probability is 90%.
D) The complement is landing on "Go Back 1 space," and the probability is 10%.

Answer 1

The complement of the event 'landing on Go Back 2 spaces' is landing on any other space, with a probability of 90%.

Step-by-step explanation:

The complement of the event 'landing on Go Back 2 spaces' is landing on any other space. So, option A) is correct.

The probability of the complement event is 90%, because the sum of the probabilities of an event and its complement must be equal to 1 (100%).
