There are three kinds of vegetation in an ecosystem: grass (G), shrubs (S), and trees (T) (Bodine, Lenhart, and Gross 2014). Every year, 25% of grassland plots are converted to shrubs, 20% of shrub plots are converted to trees, 8% of trees are converted to shrubs, and 1% of trees are converted to grass; the other transition probabilities are 0. Calculate the probability of a plot of land have the following succession of vegetation from year to year: GSGG, taking the first state as given. (type three digits after the decimal).
Answer the following question. Sammy the Seahawk is leading the Broward College (BC) Math Team in a competition against the Technical Higher Education of Mathematics (THEM). This competition consists of up to five rounds and the team that wins three rounds first wins the competition. The first round will be at BC, the second round at THEM, and the other rounds will continue to alternate locations. Sammy calculates that the probability of winning a round at BC is 0.7 and the probability of winning a round at THEM is 0.4. What is the probability that BC wins the competition? Your answer must be accurate to 5 decimal places.
Given two events G and H, the probabilities of each occurring are as follows: P(G) = 0.35; P(H) = 0.19; P(H AND G) = 0.1. Using this information: Find the complement of P (H AND G). Type answer with 0 in front of decimal to 2 places. If answer is like .2, type 0.2 not .2 or 0.20.
You have been assigned to test the hypothesis that the average number of cars waiting in line for the drive-thru window during lunch hour differs between Chick-fil-A, Wendy's, and McDonald's.

High school graduate College graduate Smoke 09 19 Do not Smoke 17 25 If an employee is selected at random, find the following probabilities. (Round your answers to three decimal places) a.

A company retains a psychologist to assess whether job applicants are suited for assembly‑line work. The psychologist classifies applicants as one of ?A (well suited), ?B (marginal), or ?C (not suited). The company is concerned about the group ?D , where an employee leaves the company within a year of being hired. Data on all people hired in the past five years give the probabilities shown. ?(?)=0.4P(A)=0.4 ?(?)=0.3P(B)=0.3 ?(?)=0.3P(C)=0.3 ?(? and ?)=0.1P(A and D)=0.1 ?(? and ?)=0.1P(B and D)=0.1 ?(? and ?)=0.2P(C and D)=0.2 Select the correct Venn diagram of the events ?,?,?,A,B,C, and ?D showing the probabilities of all combinations of psychological assessment and leaving (or not) within a year.

Exercise 4. A certain species of plant always has either three or five leaves. The number is random, with P(3 leaves) 0.4 and P(5 leaves) = 0.6. Each plant has a flower which, randomly, is either open or closed, with probabilities P(open) = 0.8 and P(closed) = 0.2. A botanist collects 1000 randomly chosen plants from this species and nds the following distribution of traits: open closed N3,closed 3 leaves N3,open 5 leaves NE,open N5, closed a) Assuming the two traits are independent, determine the expectations of the counts №3,open, N3,closed, N5,0-en, and N5,close in the table. b) Determine an approximate value for the probability P(N3,open > 340).

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
