Probability Probabilities of an event and its complement Try Again (a): Your answer is incorrect. We have a deck of 8 cards numbered from 1 to 8. 6 7 Some are grey and some are white. 1 2 13 4 8 The cards numbered 1 and 5 are grey. The cards numbered 2, 3, 4, 6, 7, and 8 are white. A card is drawn at random. Let X be the event that the drawn card is grey, and let P (X ) be the probability of X. Let not X be the event that the drawn card is not grey, and let P (not X) 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 Outcomes Event Probability 1 2 3 145 6 7 8 X X VOO P(X) not X V V V V V P (not X) - (b) Subtract. 1 - P(not X) = Explanation Recheck @2025 McGraw Hill LLC.
