The table below shows the results of a survey that asked 2868 people whether they are involved in any type of charity work. A person is selected at random from the sample. Complete parts (a) through (d) Frequently Occasionally Not at all Total Male 226 455 792 1473 Female 208 440 747 1395 Total 434 895 1539 2868 (a) Find the probability that the person is frequently or occasionally involved in charity work. P(being frequently involved or being occasionally involved) = (Round to the nearest thousandth as needed.) (b) Find the probability that the person is female or not involved in charity work at all. P(being female or not being involved) = (Round to the nearest thousandth as needed.) (c) Find the probability that the person is male or frequently involved in charity work. P(being male or being frequently involved) = (Round to the nearest thousandth as needed.) (d) Find the probability that the person is female or not frequently involved in charity work. P(being female or not being frequently involved) = (Round to the nearest thousandth as needed.)Seven of the 10!] digital video recorders [DURs} in an inventory are known to be defective. What is the probability you randomly select a DUR that is not defective? The probability is E. (Type an integer or a decimal. Do not round.) The probability that a person in the United States has type B" blood is 10%. Three unrelated people in the United States are selected at random. Complete parts (a) through (d). . . . (a) Find the probability that all three have type B* blood. The probability that all three have type B* blood is (Round to six decimal places as needed.) (b) Find the probability that none of the three have type B* blood. The probability that none of the three have type B* blood is (Round to three decimal places as needed.) (c) Find the probability that at least one of the three has type B* blood. The probability that at least one of the three has type B* blood is (Round to three decimal places as needed.) (d) Which of the events can be considered unusual? Explain. Select all that apply. O A. The event in part (a) is unusual because its probability is less than or equal to 0.05. O B. The event in part (c) is unusual because its probability is less than or equal to 0.05. O C. The event in part (b) is unusual because its probability is less than or equal to 0.05. O D. None of these events are unusual.You roll a six-sided die. Find the probability of each of the following scenarios. (a) Rolling a 4 or a number greater than 3 (b) Rolling a number less than 5 or an even number (c) Rolling a 2 or an odd number (a) P(4 or number > 3) = "Round to three decimal places as needed.) (b) P(1 or 2 or 3 or 4 or 6) = Round to three decimal places as needed.) (c) P(2 or 1 or 3 or 5) = Round to three decimal places as needed.)Decide whether the graph represents a discrete random variable or a continuous random variable. Explain your reasoning. Distance a baseball travels after being hit 200 400 600 Does the graph represent a discrete or continuous random variable? Choose the correct answer below. O A. Discrete, because distance is a random variable that is countable O B. Continuous, because distance is a random variable that is uncountable
