If Tampa hosts two of the meetings, which one of the following could be true?
medasmx@protonmail.comon January 3, 2022
dont understand please explain
for this question i get…
FALL— V T O
SPRING— T M H
i am getting this distribution from
Vs->Ts means you can have
VsTs VfTf or VfTs
so if you have two T’s you much have
FALL— V T
SPRING— T
M has to be in the spring
Hf->Mf gives…
HfMf HsMs or HsMf
HsMf is impossible since M or V must be in each of fall or spring
this leaves only HsMs which puts Of
but this is not an option
some help thanks in advance…

Hi, so for this question your reasoning in your reply isn't quite correct because remember the question is telling us that T is the repeated variable, not V.
To solve this one, we'll start by putting T in both Fall and Spring. F - T _ _ S - T _ _ Now we don't know which comes where, but we know all the other variables are not repeated, which is helpful because now we can try the scenarios. Let's put H in each group and see what happens. When we put H in Fall:
F - T H M S - T V O.
And then our other possibility is H in the Spring: F - T S - T H
O would have to go in the Fall because if it was in spring, there would be no M or V in S (breaking rule 3). Then either M or V could be the third variable in each group. So we get
F- T O M/V S- T H M/V.
All of our possibilities when T is repeated are therefore F - T H M S - T V O or F- T O M/V S- T H M/V
Options A, C, D, E are all impossible in either diagram, but B is possible if we take the second diagram and said M is in the Fall, to get:
F- T O M S- T H V. Hope this helps, feel free to follow up if you still have questions.

Im still confused as to why V doesn't have to to automatically be in the Fall because of the contrapostive of rule two where if V is in the spring then T is in the spring. Thus the contrapostive of that would be if T is in the fall then V must be in the fall.

Hi @drhall,
Rule 2 tells us that if Vspring then Tspring.
The contrapositive of theirs would actually be If T not spring then Vfall.
It is possible for T to be in both the fall and spring, so if t is in both spring and fall, v could still be in fall or spring.
