- TOPIC: PROBABILITYarrow_forward1. Probabilityarrow_forwardent Paragraph Styles The probability that a regularly scheduled flight departs on time is P(D)– 0.93, the probability that it arrives on time is P(A)= 0.82; and the probability that it departs and arrives on time is P (D N A) -0.78. Find the probability that a plane a. Arrives on time, given that it departed on time. b. Departed on time, given that it has arrived on time.arrow_forward

- Probability. Don't understand.arrow_forward(Devore: Section 2.5 #74) The proportions of blood phenotypes in the U.S. population are shown in the table. Assuming that the phenotypes of two randomly selected individuals are independent of one another. A 0.40 B AB O 0.11 0.04 0.45 (a) What is the probability that both phenotypes are O? (b) What is the probability that the phenotypes pf two randomly selected individuals match?arrow_forwardAssume that A, B and C are three independent events such that P (A) = 0.2, P (B) = 0.6 and P (C) = 0.4. Determine the probability that exactly one of these events will occur. Answer with the probability in percent.arrow_forward
- A bag contains 5 red apples and 4 yellow apples. A sample of 3 apples is drawn. Find the probability that the sample contains more red than yellow apples. The probability is? Use P(E)=n(E)/n(S).arrow_forwardAssume that A, B and C are three independent events such that P (A) = 0.2, P (B) = 0.5 and P (C) = 0.1. Determine the probability that none of these three events will occur. Answer with the probability expressed as a percentage.arrow_forwardThere are several books that teach blackjack players the "basic strategy" which increases the probability of winning any hand to 0.46. Assuming that the player plays the basic strategy, find the probability that he or she wins C. twice in 5 hands. Probability = D. 9 or more times in 26 hands. Probability =arrow_forward
