    I have a problem I hope someone can help with.

    Suppose I have a piece of paper mounted in a frame and drop, say, six identical steel balls onto it, one at a time, in different locations, from the same height. Half of them penetrate.

    How confident am I that, for a large number of such tests, the probability of penetration is 50%?

    Thanks very much.

    For a continuous real-valued parameter such as a probability, we can
    talk about our confidence that it lies within some interval, but not
    that it has some particular value. Look up binomial confidence
    interval.
