This looks like a homework problem so I'll give a hint. Your vector densPr has the probability that 0, 1, 2, ..., 10 regions will have the toad.
So if you wanted to find the probability that more than 5 regions had the toad, you would need to extract the values of densPr that meet that criteria. This isn't your problem but something similar
Thanks, I usually have problems with how to create the syntax even though I am looking for which functions to use, I think it is normal for a beginner.
I used < for an example of regions with less than 6. But in the case of 4 to 8, it must be something like 4: 8 ?, I'm lost.
