A young boy is fishing off the end of a dock. He estimates that for one out of every 15 times he casts his line, he gets at least a nibble from a curious fish. He is going to cast his line 50 times before he switches to toad hunting.

What are the mean and standard deviation of the number of successes he will have out of the 50 attempts?
