Question text Suppose that 30% of the students at your school attended a student union meeting and 25% of the students attended a faculty meeting. Also, assume that 20% of the total students attended both meetings. What is the probability that a student attended at least the student union meeting or the faculty meeting, when you consider that these two events are not mutually exclusive? Select one: a. 0.10 b. 0.25 c. 0.35 d. 0.55

Suppose that 48% of high school students would admit to lying at least once to a teacher during the past year and 25% of students are male and would admit to lying at least once to a teacher during the past year. Assume that 50% of the students are male. Suppose that you select a student from the subpopulation of liars. What is the probability that the student is female?
00 Suppose that a certain college dass contains 56 students. Of these, 31 are freshmen, 32 are business majors, and 7 are nethet. A student is selected at randem from the dass (a) What is the probability that the student is both a freshman and a business major? (b) Given that the student selected is a business major, what is the probability that she is also a freshman? write your responses as fractions. (If necessary, consult a list of formulas)...
�Martial Arts R Us� (MARU) needs a database. MARU is a martial arts school with hundreds of students. It is necessary to keep track of all the different classes that are being offered, who is assigned to teach each class, and which students attend each class. Also, it is important to track the progress of each student as they advance. Create a complete Crow�s Foot ERD for these requirements: Students are given a student number when they join the school....
Favorite snacks for high school students in Durham County are as follows: Male Female Fruit Loops 12 13 Pizza 8 15 Cookie Dough 30 12 1.) If I select one student at random, what is the probability that she will prefer pizza? 2.) What would be the probability that the student prefers Pizza, given that I select a male? 3.) What is the probability that one randomly selected student will be a female or prefer cookie dough? 4.) I am...
Question 1 (30 marks) (a) 500 adults were asked whether or not they will get married in the next 3 years. Their responses are recorded in the table. Would marry in the next 3 years Yes(Y) No (N) Male (M) 150 150 Female (F) 100 100 If one adult is selected at random from these 500 persons, find the probability that (i) the response is 'Yes'; [2 marks] (ii) the response is 'Yes' given female; [2 marks] (iii) the response...
4. Suppose an experiment consists of picking a student from the set of all students registered on the UCSD campus this quarter. It is not necessary to assume that all students are equally likely to be picked, but you may make this assumption if it makes you feel happier and more confident. (a) Consider the two events: Athe student has had four years of high school science (FYS, the student has had calculus in high school If the probability that...

Suppose that 4% of the 2 million high school students who take the SAT each year receive special accommodations because of documented disabilities. Consider a random sample of 25 students who have recently taken the test. (Round your probabilities to three decimal places.) (a) What is the probability that exactly 1 received a special accommodation? (b) What is the probability that at least 1 received a special accommodation? (c) What is the probability that at least 2 received a special...
1) Let A be the event that a student is enrolled in an accounting course, and let S be the event that a student is enrolled in a statistics course. It is known that 30% of all students are enrolled in an accounting course and 40% of all students are enrolled in statistics. Included in these numbers are 15% who are enrolled in both statistics and accounting. Find the probability that a student is in accounting and is also in...
