There were 600 students at the north campus and 400 students at the south campus.
<h2 /><h3><u>Calculus</u></h3>
To determine, if 42% of the 1000 students at the east campus are music majors, how many students did the north and south campuses have before the merger, the following calculation must be performed:
- 0.10X + 0.90Y = 420
- 1000 x 0.42 = 420
- 500 x 0.10 + 500 x 0.90 = 50 + 450 = 500
- 600 x 0.10 + 400 x 0.90 = 60 + 360 = 420
Therefore, there were 600 students at the north campus and 400 students at the south campus.

The total number of possibilities of drawing their names
is given by permutation.
4P4 = 24
The total possibility of drawing their names in
alphabetical is only 1.
Therefore the probability is:
P = 1 / 24
P = 0.0417
<span>Therefore there is about 4.17% chance that it will be in
alphabetical order</span>
