I Bernoulli Trials Homework Problem

AI Thread Summary
The discussion centers on the need for numerical answers in Bernoulli trials homework problems, emphasizing that responses should not be left in variable form (x and y). Participants highlight that teachers typically expect a single numerical value for easy grading. There is a request for clarification on how to arrive at these numerical answers, indicating a desire for more guidance. A link to a resource on Bernoulli distribution is provided to assist in understanding the calculations. The conversation underscores the importance of completing the arithmetic to achieve the final answer required for assignments.

Your answers are not answers. Numerical answers are required. You can't give answers in terms of x and y, which are variables.

can you help explain more?
 
Sometimes problems want you work it all the way to a numerical answer, a single simple value for the teacher to check. Your answer reduces it to an expression where you could’ve done the arithmetic evaluation to get a numerical answer but stopped short of that goal.

it looks like you are free to select x and y at the start.

Could you hint me how to get the numerical answer?
 

Thread 'Deductive proof in logic formal systems'

I was reading documentation about the soundness and completeness of logic formal systems. Consider the following $$\vdash_S \phi$$ where ##S## is the proof-system making part the formal system and ##\phi## is a wff (well formed formula) of the formal language. Note the blank on left of the turnstile symbol ##\vdash_S##, as far as I can tell it actually represents the empty set. So what does it mean ? I guess it actually means ##\phi## is a theorem of the formal system, i.e. there is a...
