suman is brillaint = p .. dis honest = -r so both of these joind by and means (p ^-r) suman is rich =Q  as iff and only iff is used we need to join these 2 by a double arrow .. { (p^-r)bimpliesq } as they have asked the negation so add a minus sign to the whole statement ... - {(p^-r)bimplies q}  which is option 2
