4. The class registrations of 100 students are analyzed. It is found that 50 students study Applied Mechanics, 45 study Chemistry, and 15 studied both Applied Mechanics and Chemistry (a) If one of these students is selected at random, find the probability that i. the student took applied mechanics or chemistry ii. the student did not take either of these subjects. iii. the student took chemistry but not applied mechanics (b) Are studying Applied Mechanics and studying Chemistry mutually exclusive...

In a high school graduating class of 100 students, 54 studied mathematics, 69 studied history, and 35 studied both mathematics and history. If one of these students is selected at random, find the probability that (a) the student took mathematics or history; (b) the student did not take either of these subjects; (c) the student took history but not mathematics. . . . The probability that a married man watches a certain television show is 0.4, and the probability that...
19 In a high school class, 50% of the students took Spanish, 25% took French and 30% took ncither B Let A = event that a randomly chosen student took Spanish, and B = event that a student took Frenh. Fil in cither a Venn diagram or a 2-way table and answer the questions: Fill in cither a BİB' a) Describe in words the meaning of the event AB. Find the probability of this event. b) Are the events A,...
A study on class demographics found that 60% of the students are engineering majors, 20% are mathematics majors, and 5% are studying both engineering and math. Suppose a random student from class is chosen. Let E stand for the event that an engineering student is selected and let M stand for the event that a mathematics major is selected. Suppose a random student is selected. Calculate the following. (a) P(MC) = 0.8 (b) P(E or M) = 0.75 (c) P(E...
A researcher wanted to see if live reggae music improved students’ math test scores. He selected a sample of 61 students from his university and gave them a math test. The students then studied for two and a half hours while an acoustic reggae band played quietly. The students then took another math test of the same difficulty. The researcher’s variable was the change in test score for each student — a positive change meant the student did better, while...
1. A survey will be given to 50 students randomly selected from the freshmen class at UOWD A) The 50 students B) All students at UOWD C) All freshmen at UOWD D) All students at the UK universities. 2. Researchers are concerned that the average age of a certain type of a bird is decreasing implying, among other things, that more environmental measures should be taken. If X is the age of the birds sampled in a nationwide study, then...
the case study is about the analysis of the students’ understanding in analyzing a given scenario and practical skills to apply concepts and build diagrams studied in IT242 (Software Engineering). The case study consists of five parts. Students are required to answer all these parts based on the below scenario. The SEU has adopted a blending approach to electronic learning, requiring learners to attend class lectures (25%), while 75% of course time is assigned to virtual classes, learning forums and...
