Unformatted text preview: *7, ,,,___.____________________—.\ Answer the following questions “true” or “false”. (2pts each) 16. If the sample that is generated contains a disproportionate number of instances of any particular kind, then that sample is said to be random. 17. When calculating theoretical probability, the total favorable number of events is divided by the total possible events. 18. The method of slippery slope is a variety of causal fallacies in which signiﬁcant causal factors or variables are overlooked. l9, Scatter diagrams may be used to represent Mill’s Method of concomitant variation. 20. An event is said to be dependent if the effect of either event has no effect on the probability that the other event will occur. 21. Mill’s method of difference is a principle of causal reasoning that consists of varying a suspected cause and checking for corresponding variations in the effect. 22. Plausibility is a measurement of an idea’s likelihood of surviving critical scrutiny. 23. An analogue is an event or item about which conclusions are drawn or explanations are offered by an analogy. 24. Strong statistical correlation between two events always proves that one event causes another. 25. The greater the explanatory power of a given hypothesis is, the stronger the inference. 26. Whenever a conclusion is drawn from a single premise, without reference to evidence from any other source, we call this argument an enthymeme. 27. Induction is intended to guarantee the conclusion. 28. A valid argument can have a false conclusion if the premises are true. 29.Ali valid arguments must have a true conclusion. 30. Highly unconventional, poetic pseudo-deﬁnitions of words are called etymologies. Consider the following problem. Calculate the theoretical probability of each event occurring. Place your answer in the space previded to the left of the question (2 points each) Suppose there is a box containing 10 marbles. 6 of the marbles are white and 4 of the marble are black. 31. What is the probability that on you ﬁrst pick you will pull out a white marble? (a) 1/2 (b) 3/5 (c) 2/5 ((1) 3/4 32. What is the probability that you can ﬁnd two black marbles in two consecutive picks if after the ﬁrst pick the marble is put back in the box? (a) 1/20 (b) 3/5 (c) 2/5 (ct) 4/25 33. What is the probability that that you will be able to remove all the black marbles before you draw any white marbles? (a) 1/210 (b) 3/50 (c) 2/51 (d) 9/34 34. Suppose you toss 3 coins in the air what is the probability that you will ﬁnd that after they land there are 2 heads face up? (a) 3/8 (b) 3/5 (c) 2/5 ((1) 1/2 35. Suppose you have 5 people in your ofﬁce and they have to be sent to different meetings in groups'of 3. How many different combinations of three people are possible? (a)10 (b) 12 (c) 31 (d) 7 2 /"‘ ...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
