Last Sunday I was coming back from a trip by car and I was stopped in the traffic. In that moment I was oy the seaside, and from the car I saw several people fishing, or better, standing in front of their fishing ods, waiting for a fish. I counted 10 fishermen. During the stop, I paid attention all the time in order to see when one of them catch a fish. After 12 minutes, the traffic jam resolved, and I left. During those 12 minutes, I didn't observe any fish caught by any of those 10 fishermen. A bit surprised, I asked a friend of mine, who is used to fish in that place, how many fishes are caught in average. He claims that in that place and in that conditions (hour, weather, ...) the expected number of ishes caught in 1 hour is 1 . 1) If the claim of my friend is correct, how many fishes I should expect to be caught by the 10 fishermen during my observation? 2) Which distribution better describes the probability to observe v fishes caught in that observation time (12 minutes). Write the explicit formula and calculate the standard deviation. 3) If the claim of my friend is correct, what is the probability to observe my result (0 caught in 12 minutes)? Is my observation compatible with the claim of my friend? * * Consider the result unacceptably unlikely if it there are less than 5% probability to have such result or norst.
