schaum's outline probability, random variables, and random processes pdf

In an experiment consisting of 10 throws of a pair of fair dice, find the probability of the event that at least one double 6 occurs. Since the events are mutually exclusive and from Fig. (1.38), P(A) = = 0.2 (b) Let B denote the event that the second one selected is defective. PROBABILITY [CHAP 1( t r ) Shaded region: A u H ( h )Shaded region: A nBA( I . ) (1.69)and (1.68)into Eq. (4 (b) Fig. There are such sequences, and each one of these has probability pk(l - P)\"-~.Thus, the probability that exactly k successes occur in the first n trials is given by -pyk. Let A,, A,, and A, denote the events that the switches s,, s,, and s, are closed, respectively. n Aik)= P(Ai1)P(Ai,) P(Aik) (1.51)Finally, we define an infinite set of events to be independent if and only if every finite subset of theseevents is independent. Let A = event that the tested person has the disease B = event that the test result is positiveIt is known that P(B I A) = 0.99 and P(B I A) = 0.005and 0.1 percent of the population actually has the disease. Study faster, learn better, and get top grades. If 4.i = 5, then P(B IAi)= 0. In a gambling game, craps, a pair of dice is rolled and the outcome of the experiment is the sum of the dice. (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. The desired probability is P(B n A).

Enter the email address you signed up with and we'll email you a reset link. (1.42)and the result from part (a),we obtain1.51. Let B be the event that the number of tosses required until the first headappears is odd. 1-3, we obtain +P(B) = P(556 u c65 u (66) = P G 6 ) -1P(C65) W66) = 3(&) =1.32. Suppose that A occurs for the first time at the nth trial of the experiment. Equally Likely Events: When all elementary events (5, (i = 1,2, ...,n) are equally likely, that is, p1 = p 2 = \" * - - Pn then from Eq. (c) We have P(A n B) = P[(A u B)] [Eq. Clearly all possible outcomes are all nonnegative real numbers. (a) For this experiment, the sample space S consists of 36 points (Fig. Z ) . 0:25. Since the value of X must be an integer, the value ofF,(x) for noninteger values of x must be the same as the value of FX(x)for the nearest smaller integer value of x.The FX(x)is sketched in Fig. (1.43)],we have B = B n S = B n ( A , u A, u u An) = ( B n A,) u (B n A,) u ... u (B n An) Now the events B n A,, i = 1,2, ...,n, are mutually exclusive, as seen from the Venn diagram of Fig. 1-5(a),we see that there is a closed path between a and b only if all switches s,, s,, and s,are closed. If (A,, i = 1,2, ...,n} is a sequence of mutually exclusive events, then i)P( A,) = P(AJ i= 1 i= 12. The events A,, A,, ...,A, are independent if and only if for every subset (A,,, A,, ,...,A,,) (2 5 k 5 n) of these events, .P(Ail n A,, n . 1.12. (b) Exactly one of two events occurs. Hence +P(A r\ B) 2 P(A) P(B) - 1Substituting the given values of P(A)and P(B)in Eq. (aLet S = {s,, s,, ...,s,). Find the sample space for the experiment consisting of measurement of the voltage output v from +a transducer, the maximum and minimum of which are 5 and -5 volts, respectively. A sample space S is said to be continuous if the sample points constitute a continuum (as in Example 1.3).C. 11 PROBABILITY Using Eq. 1.28), the probability that all trialsresult in successes is given byO X i) ) )P = P lim r)Ai = limp n X i = limpn= 0 p
