Eight balls numbered from 1 to 8 are placed into a bag. Some are grey and some are white. The balls numbered 1, 2, 3, 5, 6, and 8 are grey. The balls numbered 4 and 7 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 (5678 X. Let not X be the event that the selected ball is not white, 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.

K Suppose there is a 22.1% probability that a randomly selected person aged 30 years or older is a smoker. In addition, there is a 24.3% probability that a randomly selected person aged 30 years or older is male, given that he or she smokes. What is the probability that a randomly selected person aged 30 years or older is male and smokes? Would it be unusual to randomly select a person aged 30 years or older who is male and smokes? The probability that a randomly selected person aged 30 years or older is male and smokes is Would it be unusual? O Yes O No www (Round to three decimal places as needed.). wew

Consider an experiment in which a person from Valdosta State is selected at random.  Let E be the event that the person selected has brown hair, and let F be the event that the person selected is female.  Which of the following notations would indicate the probability that the person from Valdosta state has brown hair, given that the person is female?
