Hi, I have a set of 20 questions, mostly multiple choice, that need to be solved. They deal with probability in the topic of statistics. If anyone can solve them with the appropriate work there will be a small reward for this. If interested I can e-mail you the set of questions but will need all the work by 4 p.m. tomorrow. You can also call me at 9178928934. Thanks for reading and trying to help out.

With the exception of a select few output values, like a division by zero or some other undefined value, do all functions have a value?

Ignore for a second the Cartesian graph... ignore the fact that most definitions of a function require you the ability to plot a value for a given x...

What Im asking is, even if the solution isnt REAL and cant be plotted... does it exist, even if as a complex number?

for example...
Does arcsin (2) exist as a complex number? What value of theta will sin θ yield 2

Do functions exist that dont have -any- value output for a given input, even if only in theory?

Solve a[sin(x)] + b[cos(y)] = c, on the interval
(0 < or = to theta < 2pi)

NOTE: a, b and c are constants and either a does not = 0 or b does not = 0.
