[Free] a. When using the general addition rule, determine the probability that the age of the person obtained is either between 25 and 59 inclusive, or at least 35. How can the probability of this be computed without using the general addition rule? Choose the correct answer below. A. Determine the number of people with ages between 25 and 59, inclusive, or at least 35, and divide that by the total number of people. B. Determine the probability that a person chosen is between 25 and 59, inclusive, then add that to the probability that a person chosen is at least 35, then subtract from the sum the probability that the person chosen is both between 25 and 59, inclusive and at least 35. C. Determine the probability that a person chosen is between 25 and 59, inclusive, then add that to the probability that a person chosen is at least 35. D. Determine the number of people with ages between 25 and 59, inclusive, and at least 35, and divide that by the total number of people. Identify the probability of the event without using the general addition rule. The probability that the age of the person obtained is either between 25 and 59, inclusive, or at least 35 is $\square$ b. Find the probability in part (a) using the general addition rule. Identify the three probabilities used in the general addition rule. The probability that the age of the person obtained is between 25 and 59, inclusive, is $\square$. The probability that the age of the person obtained is at least 35 is $\square$. The probability that the age of the person obtained is between 25 and 59, inclusive, and at least 35, is $\square$. (Type integers or decimals rounded to three decimal places as needed) Identify the probability of the event using the general addition rule. Using the general addition rule, the probability that the age of the person obtained is either between 25 and 59, inclusive, or at least 35 is $\square$ (Type an integer or a decimal. Round to three decimal places as needed)
