Question 638260


The inverse of 'if p then q' is 'if (not p) then (not q)'

p = I do not change my car’s oil
q = my car will have engine trouble

not p = I change my car’s oil
not q = my car will not have engine trouble

So the inverse of the original statement is:
If I change my car’s oil then my car will not have engine trouble (the last one in your list).
