**Title: Probability of Drawing Queens from a Deck of Cards****Problem Statement:**Draw three cards randomly from a standard deck of 52 cards and let \( x \) be the number of queens in the draw. Evaluate the probability.**Explanation:**The problem involves calculating the probability of drawing a certain number of queens when three cards are drawn from a deck. The function \( p(x) \) is defined for values \( x = 0, 1, 2, 3 \). Each \( p(x) \) represents the probability of drawing \( x \) queens.**Probability Values:**- \( p(0) = 0.7825 \) - This value is marked incorrect.- \( p(1) = 0.2042 \) - This value is correct.- \( p(2) = 0.0130 \) - This value is correct.- \( p(3) = 0.0002 \) - This value is correct.**Conclusion:**The probabilities for drawing 0, 1, 2, and 3 queens are evaluated, with the probability for drawing no queens (\( p(0) \)) initially considered incorrect. The correct calculations would involve using combinations to figure out each scenario's likelihood, ensuring all probabilities sum to 1.

Twenty-five percent of the customers entering a grocery store between 5 P.M. and 7 P.M. use an express checkout. Consider five randomly selected customers, and let x denote the number among the five who use the express checkout. (a) What is p(5), that is, P(x = 5)? (Round the answer to five decimal places.) p(5) = (b) What is P(x < 1)? (Round the answer to five decimal places.) P(x < 1) = 0.6328 (c) What is P(2 < x)? (Round the answer to five decimal places. Hint: Make use of your computation in Part (b).) P(2 < x) = 0.3672 (d) What is P(x # 5)? (Round the answer to five decimal places.) P(x + 5) = 0.7363
Only 0.1% of the individuals in a certain population have a particular disease (an incidence rate of .001). Of those who have the disease, 90% test positive when a certain diagnostic test is applied. Of those who do not have the disease, 90% test negative when the test is applied. Suppose that an individual from this population is randomly selected and given the test. Use the general multiplication rule to calculate P (has disease AND positive test) and P (no disease AND positive test). Calculate P (positive test) and P (negative test). Calculate P (has disease | positive test). Does the result surprise you? Give an intuitive explanation for why this probability is small.
An electronics store has received a shipment of 20 table radios that have connections for an iPod or iPhone. Ten of these have two slots (so they can accommodate both devices), and the other ten have a single slot. Suppose that six of the 20 radios are randomly selected to be stored under a shelf where the radios are displayed, and the remaining ones are placed in a storeroom. Let X = the number among the radios stored under the display shelf that have two slots. (a) What kind of distribution does X have (name and values of all parameters)?

I roll a die with 10 faces numbered 0-9 and obtain a score X. What is E(X)? In order to obtain a random number between 0 and 99 I roll the die twice obtaining scores X and Y, then set Z = 10X + Y (i.e., the first roll determines the "tens", the second roll the "ones"). Is it true to say that E(Z) = 10E(X) + E(Y)?
