+Let A, B, and C be the events that the player wins, the player wins on the first roll, and the player gains point, respectively. Finite stochastic processes and tree diagrams. 1-41.7. One deck of cards is laid out in a fixed order, and the other deck is shufkd and the cards laid out one by one on top of the fixed deck.

PROBABILITY [CHAP 1( t r ) Shaded region: A u H ( h )Shaded region: A nBA( I . ) Find the probability of getting a match at the first four positions. (1.l9). (a) In order to find the probability of at least 1 success in the first n trials, it is easier to first compute the probability of the complementary event, that of no successes in the first n trials. 1.34, pi = i = 1, 2, 3, 4, where pi is the probability of failure of switch si.

(1.44).Suppose that a laboratory test to detect a certain disease has the following statistics. Then the number of outcomes belonging to A is Assuming that each outcome is equally likely, then by Eq. Suppose that P({a, c ) )= 0.75 and P({b, c)) = 0.6. Wedlinehorton. An urn contains 8 white balls and 4 red balls. B ) , we obtain P(A n B) = P(A)- P(A n B) = P(A)- P(A)P(B) = P(A)[l - P(B)] = P(A)P(B) Thus, by definition (l.46), A and B are independent. This Schaum's Outline gives you. (1.go),Using these values, we obtain Supplementary Problems1.64. An experiment consists of tossing two dice. Thus,(1, 2) (1, 3) (1, 4)(2, 1) (2, 3) (2, 4)(3, 1) (3, 2) (37 4)(4, 1) (4, 2) (4, 3)1.3. 11 PROBABILITYWe may also extend the definition of independence to more than three events. Probabilities—Problems, exercises, etc. 2. Consider the experiment of throwing the two fair dice of Prob. — (Schaum's outline series) Includes index. A sequence of Ber- noulli trials occurs when a.Bernoulli experiment is performed several independent times so that the probability of success, say p, remains the same from trial to trial. (1.85), the probability of failure for the combination of switches 2, 3, and 4 is i)p234= 1 - (1 - 4x1 - =; 1 - 38 = 8 Again, using Eq. Intersection: The intersection of sets A and B, denoted A n B, is the set containing all elements in both A and B. CHAP. Disjoint Sets: Two sets A and B are called disjoint or mutually exclusive if they contain no common element, that is, if A n B = 0. Ans. (a) For this experiment, the sample space S consists of 36 points (Fig. 1-5(c), we see that there is a closed path between a and b if s, and either s, or s, are closed.Thus, A,, = A, n (A, v A,)Using the distributive law (1.12),we have A,, = (A1 n A,) u (A, n A,)which indicates that there is a closed path between a and b if s, and s, or s, and s, are closed.From Fig. (1.81) is true for n = 2. If the sum is 4, 5, 6, 8, 9, or 10, that number is called the player's \"point.\" Once the point is established, the rule is: If the player rolls a 7 before the point, the player loses; but if the point is rolled before a 7, the player wins. 21 RANDOM VARIABLES2.4 DISCRETE RANDOM VARIABLES AND PROBABILITY MASS FUNCTIONSA. Since the dice are fair, all the outcomes are equally likely. Plant 1 produces 1,000 parts, 100 of which are defective. (a) Let A c S, be the event defined by X = 2. Again from Fig. Schaum’s Outline of Probability, Random Variables, and Random Processes, Fourth Edition is packed with hundreds of examples, solved problems, and practice exercises to test your skills. (b) Exactly one of two events occurs. Let A be the event that there exists a closed path between a and b. Union: The union of sets A and B, denoted A u B, is the set containing all elements in either A or B orboth.4. — (Schaum's outline series)Includes index.ISBN 0-07-030644-31. Show that P(A) = P(A n B) + P(A n B) From the Venn diagram of Fig. (a) Let A be the event that two faces are the same. Complementation: Suppose A c S. The complement of set A, denoted A, is the set containing all elements in S butnot in A. A= {C: C: E Sand \$ A)3. (1.63),we get P(A n B) 2 0.9+ 0.8 - 1 = 0.7Equation (1.63)is known as Bonferroni's inequality.1.23. (1.64)(Prob. Note that the terminology used here is traditional. 2 Verify Eq. (b) There are four possible outcomes. 1) PROBABILITYShow that for any events A and B in S, P(B) = P(B I A)P(A) + P(B IA)P(X) From Eq. only if its range contains a finite or countably infinite number of points. Elementary Properties of Probability: By using the above axioms, the following useful properties of probability can be obtained:6. Figure 1-6 shows the sequence of relevant Venn diagrams.
