An experiment consists of two independent trials. The outcomes of the first trial are A, B, and C, with probabilities of occurring equal to 0.3, 0.3, and 0.4, respectively. The outcomes of the second trial are E and F, with probabilities of occurring equal to 0.5 and 0.5. 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

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).
blindness. Would these results be surprising? Explain why or why not. 4) At the end of basketball practice, each player on the team must shoot free throws until he makes 10 of them. Slim is a 70% free-throw shooter. That is, his probability of making any free throw is 0.70. Given this information, the dotplot below shows a simulation of 120 trials of shooting 12 free throws with a 0.70 chance of making any free throw. : 4 : 5 6 8 9 7 Number of Made Free Throws 10 11 red-green color 12 a) Explain what the two dots at 5 represents. b) Use the simulation to estimate the probability that Slim makes 10 or more free throws. 3 1297091 c) Based on the results from the simulation, how many free throws is Slim most likely to make in 12 attempts? d) Therefore, based on your answer to part (c), how many total attempted free throws do you predict Slim will have to take before he can finish practice and go home.
