If P(x)=0, this means that A. The event X might occur. B. The event X will occur C. The event X will never occur

Decide whether the following pairs of events are dependent or independent C is the event that it rains more than 10 days in Chicago next June, and D is the event that it rains more than 15 days.

For this problem, assume that Pr[A∪B]=0.85and Pr[A]=0.3. (1) What is Pr[B]Pr[B] if A and B are independent events?  (2) What is Pr[B]Pr[B] if A and B are disjoint events?

Which of the following statements is true? Select one of the options i. – iv.The probability of an event that is certain to occur is equal toi. -1ii. 0iii. 1iv. None of the above.

Given 2 events, A and B. Suppose P(A) =0.6 and P(B)=0.6. Which one of the following statements must be correct? Select one: O OO O O a Event A and Event B are the same event. b. Event A and Event B can not be mutually exclusive c. P(A and B) 0.6

A student goes to the library. Let event A be that the student checks out a book and event B be that the student uses a library computer. Suppose that we happen to know that P (A) = 0.40, that P (B) = 0.30, and that P (B|A) = 0.5. Compute the following (1) P(Ac)(2) P(A AND B) (3) P(A|B)

P(A) + P(B) = 1 for any events A and B that are mutually exclusive.    True  False

Let A and B be two events with P(A and Bc) = 1. Find P(B). Recall that Bc denotes the complement of the event B.

A study was conducted to examine how anxiety (measured on a metric scale) varies for people from different age groups (<18 years, 19 - 29 years, 30 - 39 years, 40+ years). It was hypothesised that people <18 years old would have the least anxiety of the four age groups. It was also hypothesised that people 40+ years old would have more anxiety than people 19-29 years old. Which of the following would be an appropriate statistical test to conduct, which addresses these hypotheses? Group of answer choices: Factorial ANOVA Multiple Regression Mixed ANOVA Single factor ANOVA Within Subjects ANOVA

9. E and F are two events such that P(E) = 0.60, P(E or F) = 0.90 and P(E and F) = 0.50. Find P(F).
