jim_thompson5910 · Answer

In general, if P(X) = k, where X is any event, then 

0 <=  k  <= 1

jim_thompson5910 · Answer

basically, the probability of any event is always between 0 and 1 (to represent the chances of 0% and 100%)

anonymous · Answer

so always

jim_thompson5910 · Answer

P(A and B) is __always__ greater than 1.

is that true?

anonymous · Answer

yes

jim_thompson5910 · Answer

go back to what i just wrote

anonymous · Answer

so it is

jim_thompson5910 · Answer

no it's not, you can't have a probability greater than 1

anonymous · Answer

so its not always

jim_thompson5910 · Answer

no more like "never"

anonymous · Answer

oh thank you
