Question: Gigacorp Managers

Comment on Gigacorp Managers

Tricky I would have chosen 60 at first after reading female MBA manager . But reading question is quite essential with details

Agreed!

Why dint we do 60/250 ?

Great question!

If you feel the answer is 60/250, then you are answering a different question from the one that is asked.

Among the 250 managers at Gigacorp, 60 are females with MBAs.
so, IF the question were "What percent of ALL MANAGERS are females with MBAs?", then the correct answer would be 60/250

However, the question actually asks "What percent of the FEMALE MANAGERS have MBAs?"

There are 150 FEMALE MANAGERS
Among those 150 FEMALE MANAGERS, 60 have MBAs
60/150 = 40%

Does that help?

When setting up the matrix, does it matter which sides (top vs side) you use for which items? I did my matrix the opposite that is shown in the video (m/f on top and mba/~mba on the side) and I came to the same conclusion as shown.

Good question.
It makes no difference which sides you use.

Cheers,
