Given the new fad of health consciousness, a random sample of 400 college students was asked what their preferred type of drink was and whether they took regular or sugar free. The following table gives a two-way classification of the responses. Regular Sugar free TOTALS Juice 210 95 305 Iced Coffee 75 20 95 TOTALS 285 115 400 (a) If one student is selected at random from these 400 students, find the probability that this student (i) Prefers sugar free drinks (ii) Prefers juice (iii) Prefers regular juice (iv) Prefers juice given that it is a sugar free drink. (v) Prefers iced coffee or that drinks must be sugar free. (b) Are the events 'prefers juice' and 'prefers sugar free drinks' independent? Use probabilities to state your answer.

The accompanying tree diagram represents a two-stage experiment. (Let x = 0.3, y = 0.7, r = 0.7, s = 0.3, t = 0.4, and w = 0.6.) Use the diagram to find the following probabilities. (Round your answers to three decimal places.) (a) Find P(A) · P(D | A).(b) Find P(B) · P(D | B).(c) Find P(A | D).
In a survey of readers of a US Weekly magazine a question was asked, “Which do you prefer: Facebook or Twitter?” There were 362 responses from females and 216 responses from males. 281 females and 98 males stated they prefer Facebook. Use proper notation to state the probabilities. (a) Create a two-way table to organize the responses to the survey. Determine the totals of the rows and columns. (b) Define events F: the survey response was from a female and T: the survey response was from a person who preferred Twitter. Create a Venn Diagram to organize the responses to the survey. (c) What is the probability that a randomly selected reader is female and prefers Twitter? (d) Of the respondents who prefer Twitter, what is the probability that the respondent is female? (e) Suppose a female reader is selected at random, what it the probability that she prefers Twitter? (f) Are the events being female and preferring Twitter independent? (g) Are the events being female and preferring…
An experiment consists of two independent trials. The outcomes of the first trial are A, B, and C, with probabilities of occurring equal to 0.2, 0.4, and 0.4, respectively. The outcomes of the second trial are E and F, with probabilities of occurring equal to 0.7 and 0.3. Draw a tree diagram representing this experiment. Use this tree diagram to find the probabilities below. (a) P(B)(b) P(F | B)(c) P(B F)(d) P(F)(e) Does P(B F) = P(B) · P(F)? YesNo (f) Are B and F independent events? YesNo
