Thanks Alan, ... but it doesn't help me.

I graphed it too, but I have no idea how to answer the question.

Calculate sin(sin(X)). Plot this point on the graph. Draw a horizontal line from -10pi to 10pi at this level.

Now calculate sin(sin(Y)). All we know is that it must be *on the same* horizontal line as well as on the curve.

There are 20 possible values of sin(sin(Y)) that are the same as sin(sin(X)).

Hence the probability that X = Y is 1/20.

(At least, I think that's the interpretation of this question!).
