Wasn't sure what to call this.. .But here goes I am having trouble solving the following questions, here is the first, and how I have gone about it
The daily probability of sighting a landscape bird near the lake is 0.3. What is the probability that the next sighting occurs five days from now?
Using Geometric Probability
I (think this is correct) can calculate like so, the first question,
This yields the result of
P(X=5) which I think is correct.
However my main problem is the question after it which is,
What are the mean and standard deviation of the time until the next landscape bird is seen?
So my question is how can I calculate the mean and standard deviation using the information I have? I am used to calculating it from a graph or table of statistics...
Any help would be appreciated
