Question 184165
Let P=we have a rock concert and Q=Someone will faint



Original Statement: "If we have a rock concert, someone will faint." translates to if P then Q



Converse: Simply switch P and Q to get: if Q then P


So the converse is: "If someone will faint, then we have a rock concert"


------------------


Inverse: Take the original statement "if P then Q" and change it to "if NOT P then NOT Q" (ie negate everything)



So the inverse is: "If we don't have a rock concert, then someone will not faint"



--------------------


Finally, contrapositive: Take the converse "if Q then P" and negate everything to get "if NOT Q then NOT P"


So the contrapositive is: "If someone will not faint, then we don't have a rock concert"
