five balls numbered from 1 to 5 are placed into a bag.
Some are grey and some are white.
The ball numbered 1 is grey.
The balls numbered 2,3,4, and 5 are white.
A ball is selected at random.
Let X be the event that the selected ball is white, and let P(X) be the probability of X.
Let not X be the event that the selected ball is not white, and let P(notX) be the probability of not X.
(a) For each event in the table, check the outcome(s) that are contained in the event. Then, in the last column, enter the probability of the event.
(b) Subtract: 1-P(X)=
(c) 1-P(X) is the same as
