boolean logic - comparing three booleans

I'm trying to construct a method to answer the below question. However I'm having a bit of trouble. Can someone assist me with this logic?

Write a static method odd() that takes three boolean inputs and returns true if an odd number of inputs are true, and false otherwise.

public boolean odd(boolean a, boolean b, boolean c)
    {   
        if((a && b) && (b && c) && (a && c))
            return true;
        if((a && b) && (b && c) || (a && b) && (a && c))
            return false;
         return false;
    }
