Question 1190871: How many courses? At a small liberal arts college, students can register for one to six courses. Let X be the number of courses taken in the fall by a randomly selected student from this college. In a typical fall semester, 6% take one course, 6% take two courses, 12% take three courses, 20% take four courses, 41% take five courses, and 15% take six courses. Let X be the number of courses taken in the fall by a randomly selected student from this college. Describe the probability distribution of this random variable.
-->Use a probability histogram to provide a graphical description of the distribution of X.

X = number of courses taken

This is what the probability histogram would look like

The height of each bar is the decimal version of the percentages listed.
Example: 41% = 0.41
There are no spaces between each bar in a histogram.

You can use Excel to make such a histogram, or use free software similar to it. I used the LibreOffice spreadsheet program to make the diagram above.

If you need the probability distribution as a table, then it could look something like this

X	P(X)
1	0.06
2	0.06
3	0.12
4	0.20
5	0.41
6	0.15
