If an event has a probability P of happening, then there is a probability of (1-P) of the event not happening.
In this case the probability of the event is p=20/69.
Then, the probability of the event not happening is:

Answer: the probability of the event not happening is 49/69.
The coordinates of C' are 3 times those of C.
3×(2, -1) = (6, -3)
The appropriate selection is ...
(6, -3) . . . . . . . . . the 4th one
