Homework Statement
I have been given a CDF of T value probabilites for t >= 0
I have been given P(t=3)=0.59 P(t=5)=0.85
Homework Equations
The Attempt at a Solution
I have been asked to find P(T > 5 | T>3 )
I was wondering how to work this out.
As this is a conditional probabilty I was heading towards
P(T > 5 | T>3 ) =
[itex]
\frac{P(T > 5 \and T>3 )}{P(t>5)}[/itex]
so the probabilty of P(T > 5 \and T>3 )} = .41
and P(t>5) = .15
But you can't use that calculation.
But wouldn't the probability of of being > 5 still just be .15
Any help would be appreciated
