The proportion of outcomes that can be expected to be observed during a short experiment. The proportion of times the outcome would occur in a very long series of repetitions. The proportion of repetitions that result in the outcome when an experiment is conducted about the random phenomenon. Use the following to answer questions 38–39: A standard deck of cards has 52 cards. The cards have one of 2 colors: 26 cards in the deck are red and 26 are black. The cards have one of 4 denominations: 13 cards are hearts (red), 13 cards are diamonds (red), 13 cards are clubs (black), and 13 cards are spades (black). 38. One card is selected at random and the denomination is recorded. Which of the following is the correct sample space S for the set of possible outcomes? A) S = {red, black} B) S = {red, red, black, black} C) S = {hearts, diamonds, clubs, spades} D) S = {red, black, hearts, diamonds, clubs, spades} 39. Two cards are selected at random and the color is recorded. Which of the following is the correct sample space S for the set of possible outcomes? A) S = {red, black} B) S = {(red, red), (red, black), (black, red), (black, black)} C) S = {0, 1, 2} D) S = {red, black, hearts, diamonds, clubs, spades} 40. Two cards are selected at random and the denomination is recorded. The event H is defined as the event that the first card is hearts. Which of the following correctly defines event H? A) H = {diamonds, clubs, spades} B) H = {hearts, diamonds, clubs, spades} C) H = {(hearts, diamonds), (hearts, clubs), (hearts, spades)} D) H = {(hearts, diamonds), (hearts, clubs), (hearts, spades), (hearts, hearts)} 9 J Diaco Elements of Statistics I Supplemental Final Exam Review 41. A) B) C) D) Two cards are selected at random and the denomination is recorded. The event D is defined as the event that the first card is diamonds and the second card is red. Which of the following correctly defines event DC? DC = {(diamonds, clubs), (diamonds, spades)} DC = {(hearts, clubs), (hearts, spades)} DC = {(hearts, clubs), (hearts, spades), (spades, clubs), (spades, spades), (clubs, clubs), (clubs, spades)} None of the above. 42. A) B) C) D) Two cards are selected at random. Event C is defined as the event that the first card is clubs, event R as the event that the first card is red, and event B as the event that the second card is black. Which events are disjoint? R and B only. R and C only. R and B, R and C, but not B and C. None of the events are disjoint. Use the following to answer questions 43–46: Consider the following probability histogram for a discrete random variable X: 43. A) D) This probability histogram corresponds to which of the following distributions for X? Value of X 1 2 3 4 5 Probability 0.06 0.25 0.38 0.25 0.06 Value of X 1 2 3 4 5 Probability 0.10 0.25 0.30 0.20 0.15 Value of X 1 2 3 4 5 Probability 0.10 0.25 0.30 0.25 0.10 None of the above. 44. A) B) What is the P(X = 3)? 0 0.20 B) C) C) D) 0.25 0.30 10 J Diaco Elements of Statistics I Supplemental Final Exam Review 45. A) B) What is P(X < 3)? 0.10 0.25 C) D) 0.35 0.65 46. A) B) What is P(X ≤ 3)? 0.10 0.25 C) D) 0.35 0.65 Use the following to answer questions 47 and 48: Let the random variable X represent the profit ma...
