Killer MM

Management Math paper was a killer i tell you.

KILLER spelt with a capital K!!!! Arghh.... make me wake up so early in the morning somemore.

The set theory was so freakin hard! I dun give a damn who's vegetarian, or who have excess baggage, or who smokes, or who freakin sits the economy/business/first class la!! ARGH.

This was the qn:

• an airline has 3 classes of passengers denoted as economy (E), business class (B), and first class (F).
• Economy and business class passengers sometimes have excess baggage (X), whereas first class passengers never have excess baggage.
• All passengers who smoke (S) travel economy class but never have excess baggage.
• Vegetarians (V) never travel first class and do not smoke.

Interpret each of the above statements in set notation and hence construct a single Venn diagram to illustrate the relationship between B,E,F,S,V and X. (10m)

- stumped -

And juz when it suddenly hit me that B,E and F does not intersect (how stupid of me), time's up. Grreat. And that was only the first part.

And the matrix qn that was suppposed to be tedious and easy... was tedious AND difficult. WTH.

Bleah~ Enough deploration. I'm off to play rose... to vent my frustrations...
