A camera has been lost in the forest, a group of friends are organizing an expedition to find it back (summary of the previous parts of the problem).
While searching for the camera, a parc ranger appears and tells the group that there has been 9 random sightings
of a wild boar in the past 2 days and that they must take extra caution.
Assume they will end their day of search in at most three more hours, approximate the probability a wild boar appears before they find the camera during the next three hours. State any assumptions used in the calculation.
I think the underlying distribution to describe the sighting of boars is an Exponential Distribution $\lambda e^{-\lambda t}$, but the part that throws me of is how to take the finding of the camera into account
($P(X < 3\mid Camera\ not\ found)$ ? ).
Note that the probability for finding (or not) the camera has not been previously given.. (Makes it all the more confusing to me)
Thank you :)
