hi,
well i've just started to mess around the probabilities and the problem i don't understand is :

if a probability for a person to finish his work in x hours is x/2 . i need to prove that him finishing his work in one hour, after 45 min of working on the problem is 0.2.

and i don't know how to prove that. can somebody help me

thnx

:)

pro x/2

obviously the probability of finishing work within x hours (x<=2 hr) otherwise the probability will go above one. Can you please check your question?
