Which of the following is the correct expression for symmetric binary dissimilarity between two objects, where q and t attributes have value 1 and 0 for both objects respectively, r attributes have value 1 for first object and 0 for the second object and s attributes have value 0 for the first object and 1 for the second object?
Dissimilarity = (r + s)/ (q + r + s + t)
Dissimilarity = (q – s)/ (q + r + s + r)
Dissimilarity = (t + s)/ (q + r + s + t)
Dissimilarity = (r – s)/ (q + r + s + t)
