When randomly selecting an adult. A denotes the event of selecting someone with blue eyes. What do PA) and P (A) represent? P(A) represents the P (A) represents the
Decide if the events are mutually exclusive. Event A: Randomly selecting a nurse Event B: Randomly selecting a male Are the two events mutually exclusive? O A. No, because someone who is a nurse can be male. B. No, because someone who is a nurse cannot be male. ° C. Yes, because someone who is a nurse can be male D. Yes, because someone who is a nurse cannot be male
Consider randomly selecting a student at a large univer- sity, and let A be the event that the selected student has a 12. Visa card and B be the analogous event for MasterCard. Suppose that PCA) = .6 and P(B) = .4. a. Could it be the case that PA N B) 5? Why or why not? lHint: See Exercise 24.] From now on, suppose that P(A n B)-.3, what is the probability that the selected student has at least...
Probability 3. Sample for a Poll There are 15,524,971 adults in Florida. If The Gallup organization dependent? dependent, can they be treated as being independent for the purposes of ran- domly selects 1068 adults without replacement, If the selections are are the selections independent or calculations? 4. Rule of Complements When randomly selecting randomly selecting someone with type B blood. Write a sentence describing what the rule of complements is telling us: P(B or B) 1. an adult, let B...
Consider randomly selecting a student at a certain university, and let ? denote the event that the selected individual has a Visa credit card and ? the analogous event for a MasterCard. Suppose that ?(?) = 0.5, ?(?) = 0.4, and ?(? ∪ ?) = 0.65. a. What is the probability that the student has both types of cards? b. What is the probability that the student has a MasterCard but not a Visa? c. What is the probability the...
Consider randomly selecting a student at a large university, and let A be the event that the selected student has a Visa card and 8 be the analogous event for MasterCard. Suppose that P(A)-0.6 and P(B)-0.4 (a) Could it be the case that PLA n B)-0.5 ? why or why not? [Hint: For any two sets A and B d'A is a subset of B then AAS pu).] No, this is not possible. Since A ก B is contained in...
randomly selecting a student at a large university. Let A be the event that the selected student has a Visa card, let 8 be the s event for MasterCard, and let C be the event that the selected student has an American Express card. Suppose that Pe n C)-0.1, and P(A n BnC)-0.08 A)-0.6,代8)-04, and (a) What is the probability that the select ed student has at least one of the three types of cards? (b) What is the probability...
The probability of the event "blue eyes" is currently 0.35 for children born in USA. Let us define the random variable x to be the number of “blue eyes” children among 10 children born in Orlando. (a) Find the probability that x is less than 5. (b) What is the probability that x is between 2 and 4 inclusive?
Consider randomly selecting a student at U of T, and let denote the event that the selected student has a Visa credit card and be the analogous event for a Master Card. Suppose that , and . c) What is the probability of the event that the selected student has a Visa Card but does not have a Master Card?

If A denotes some event, what is the notation of the complement of the event A? If P(A) is 0.995, what is the probability of the complement of A? Is the complement of A unusual? Why or why not?
