A mouse, released in A, wants to reach her food in point C. A cat sleeps on the crossroads B. If the mouse passes B, it will be eaten by the cat. Calculate the probability that the mouses reaches her food alive!
is this a trick one? The answer is 100% because she could only reach her food if she was alive. If she was dead she wouldn't get there, so; the probability of her reaching her food alive is 100%.
