Number of ways of choosing two pair of sneakers from three pairs named A, B, C is given by 3C2 (3 combination 2) = 3! / 2!(3 - 2)! = 3! / (2! x 1!) = (3 x 2) / (2 x 1) = 3.
Therefore, the sample space is given by S = {AB, AC, BC}
Response/ NonResponse: Some students might be too tired to answer the question or in converse, a student might feel that his or her grade might be reflected on the survey since it is not anonymous, he or she might sugarcoat the answer. (incorrect response bias)
Answer:
The answer is A (i just took the test)
Step-by-step explanation:
Answer: The outcomes do not appear to be equally likely, so a uniform probability model is not a good model to represent probabilities in Pilar's experiment
The outcomes are: 1 2 3 4 5
The Relative Frequency: 0.05 0.35 0.26 0.13 0.21
As you can see the outcomes do not appear to be equally likely since 0.05 and 1 are not close in number range along with the other options
B + (-60) = -14
-60 -60
---------------
b = -74
What error, if any, did Maureen make?
Maureen's work is correct, and her original balance was -$74.
Maureen should have added 60 to both sides.
Maureen should have added 14 to both sides.
Maureen made a computational error when she subtracted -14 - 60
