    Interesting probability problem

    are you sure you can differentiate w.r.t. p this equation looks like the expectation of a geometric series which I posted at https://www.physicsforums.com/showthread.php?t=70705

    Connectives Homework: Incomplete Set, Propositions P & Contradictions

    quoted from [PLAIN]www.ida.liu.se/~TDDB08/2005/slides/l5-6.pdf[/URL] but this is not a very good reference for it. <<< Sheffer in 1913 provided a connective, called the Sheffer stroke and denoded by |, which is suffcient to express any other connective in the case the of two-valued...

    Calculating Probability of Sixth Die Face on Nth Consecutive Throw

    a related problem is what is the the expected number of throws to get a six on a fair dice this was raised at https://www.physicsforums.com/archive/topic/t-45262_The_expected_value_of_a_Geometric_Series.html which seems to be closed now. yes the answer is 6 but how do you prove it...

    Ordinal Exponentiation Comparison

    going back to which is greater a^b or b^a. ( i can't use the special symbols) then assume a>b (without loss of generality) then if b=1 then a^b =a b^a =1 so a^b is greater there are some special cases for a,b, <=3 which I leave you to find but for all other cases b^a is greater...
