If the probability of an event changes after another event has already occurred, the events are:...
A real estate broker studied apartment prices. The highest-priced apartments increased in value while the rest of the prices remained the same. How should he expect the statistics to change? A. All of the statistics would change B. The median and interquartile range would change; the mean and standard deviation would not change C. The mean and standard deviation would change; the median and interquartile range would not change D. None of the statistics would change 2. If the probability...
You are approaching a traffic signal. If the probability of encountering a red light is 0.50 and the probability of seeing a green light is 0.40, what is the probability of encountering a yellow light? 0.90 0.10 0.001 0.20 If 60% of students have an iPhone, 30% have an iMac computer, and 20% have both an iPhone and an iMac, how may students could be identified as an Apple customer having either an iPhone or iMac? 0.90 1.10 0.20 0.70...
The probability of event A occurring given that event B has already occurred is 0.61. The probability of both events occurring is 0.5. What is the probability of event B occurring? O 0.305 O 0195 O 0.390 O 0.820 O 0.500
3. If PA)-03, P(B) 0.2, P(A and B)-a06, what can be said about events A and B ? A) They are independent. B) They are mutually exclusive. C) They are posterior probabilities. D) None of the above E) All of the above 4. "The probability of event B, given that event A has occurred" is known as a probability A) continuous B) marginal C) simple D) joint E) conditional 5. The expected value of a probability distribution is A. the...
Two events, A and B, are mutually exclusive and each has a nonzero probability. If event A is known to occur, the probability of the occurrence of event B is A.One B.Any positive value C.Zero D. Any value between 0 to 1 Suppose that the probability of event A is 0.2 and the probability of event B is 0.4. Also, suppose that the two events are independent. Then P(A∩B) is: a.P(A) = 0.2 b. P(A)/P(B) = 0.2/0.4 = 0.05 c....
The probability of the second event in the situation if the first event has occurred is classified as A. series probability B. conditional probability C. joint probability D. dependent probability
Events A and B are mutually exclusive. Suppose event A occurs with probability 0.27 and event B occurs with probability 0.09. If event A or event B occurs ( or both), what is the probability that A occurs? Round your answer to at least two decimal places.
Events 4 and B are mutually exclusive. Suppose event A occurs with probability 0.5 and event B occurs with probability 0.41 a. Compute the probability that B occurs or A does not occur (or both). b. Compute the probability that neither the event A nor the event B occurs.
Which rule of probability states that for two non-mutually exclusive events the probability of each event occurring is equal to the sum of their separate probabilities minus the probability of their joint occurrences? Bounding rule of probabilities Restricted multiplication rule of probabilities General addition rule of probabilities Restricted addition rule of probabilities
Events A and B are mutually exclusive. Suppose event A occurs with probability 0.04 and event B occurs with probability 0.52. Compute the probability that B occurs or A does not occur (or both).Compute the probability that either A occurs without B occurring or A and B both occur.
