Repeat the analysis in part (b) assuming that the rules have identical support. Which rule has the highest confidence?

What will be an ideal response?

Considering s(p ? q) = s(p ? q ? r)
but s(p) ? s(p ? r)
Thus: c3 ? (c1 = c2)
Either all rules have the same confidence or c3 has the highest confi-
dence.
