Thirty-three percent of adults did not visit their physicians' offices last year. Let X be the number ofadults in a random sample of twelve adults who did not visit their physician's office last year. LetP₁, P2, P3, and P4 be the probabilities, respectively, that the number of adults who did not visittheir physician's office last year will be:• exactly one;• two or more;• fewer than four;• between five and six, inclusive.Then the values of P₁, P2, P3, and P4 are, respectively, (Choose one from the following which isclosest to the correct answer)O a. 0.0484, 0.8124, 0.4027, 0.2958.O e. 0.0565, 0.8124, 0.4027, 0.2958.O b. 0.0484, 0.9435, 0.4027, 0.1079.O d. 0.0484, 0.9435, 0.6410, 0.2958.c. 0.0484, 0.9435, 0.4027, 0.2958.

Consider three classes (I, II and III) consisting of 30, 25, and 45 students. Suppose a student is selected from class I, then he has 10% chance to make an A. Assume that these probabilities for the class II and III are 15% and 20% respectively. If a student is selected randomly and has an A, what is the probability that he is from class II. Enter your answer to the nearest FOUR decimal places.
Each participant in an experiment was given one of three tasks. Let these three tasks be symbolized by A1,A2, A3 . The number of errors each participant made in performing the task was recorded by use of the categories “0 errors,” “1 error,” and “2 or more errors.” Thus, every participant was classified in two ways, by task and by number of errors. The following table shows the probabilities for these joint events for any participant drawn at random. Task Errors A1 A2 A3 Total 0 .05 .02 .13 .20 1 .08 .17 .10 .35 2 or more .20 .15 .10 .45 Total .33 .34 .33 Use these probabilities to find: The marginal probabilities of the task events A1,A2, A3 The marginal probabilities for numbers of errors The conditional probability for zero errors given task A1 The conditional probability for two or more errors given task A2 The conditional probability of task A3 given no errors
Approximately 20% of U.S. workers are afraid that they will never be able to retire. Suppose 10 workers are randomly selected. a. What is the probability that none of the workers is afraid that they will never be able to retire?
A person draws a card from a hat. Each card is one color, with the following probabilities of being drawn: 1/25 for pink, 1/10 for blue, 1/20 for red, and 1/15 for yellow. What is the probability of pulling a blue or red card, written as a reduced fraction?
In a survey of consumers aged 12 and older, respondents were asked how many cell phones were in use by the household. (No two respondents were from the same household.) Among the respondents, 211answered "none,"289 said "one," 373 said "two," 143 said "three," and 138 responded with four or more. A survey respondent is selected at random. Find the probability that his/her household has four or more cell phones in use. Is it unlikely for a household to have four or more cell phones in use? Consider an event to be unlikely if its probability is less than or equal to 0.05.
The athletic department of a school has 13 full-time coaches, and 4 of them are female. The director selects two coaches at random from this group. The probability (to three decimal places) that neither of them is a female is:
A gas station has three grades of fuel, regular, premium and diesel. Due to problems with the supply chain, the probabilities that the station will run out of any three fuel types in a week are 0.10, 0.16 and 0.24, respectively. These probabilities are statistically independent. Also, if there is a shortage of diesel, the probability of a shortage of premium becomes 0.25. 1. How likely is the station to run out of all three fuels in a given week? 2. What is the probability that if regular runs out, both premium and diesel will also run out? 3. What is the probability that the station will run out of at least one of either premium and diesel? 4. What is the probability that the station will run out of at least 2 of the fuels in a week?
