1) You own 6 songs by Adele, 4 by Katy Perry, and 5 by Lady Gaga. How many different playlists can you make that consist of 4 Adele songs, 3 Perry songs, and 2 Gaga songs, if you do allow repeated songs?
2) Kevin and Walter can't stop discussing their Probability course at every opportunity, which has been very disruptive of the regular discussions at the CCIS Teaching Seminar. Martin, who organizes the seminar, must now calculate the number of ways in which he can arrange the 10 participants in a line so that Kevin and Walter aren't sitting next to each other. What is that number?
3) In a race with 6 runners, how many possible finishing orders are there?

You have been given a ticket to see Katy Perry in concert
tonight. You cannot resell the ticket. Adele is performing on the
same night & her concert is the only other activity you are
considering. An Adele ticket costs $85 & on any given day you
would be willing to pay as much as $150 to see her play. There is
no other cost of seeing either performer.
What is the opportunity cost of attending the Katy Perry
concert?...

A playlist contains 15 songs, 5 songs from Artist 1, 5 songs
from Artist 2, and 5 songs from Artist 3. Shuffle the playlist
(randomly) and listen to the first 6 songs on the playlist. Let Y1
be the number of songs from Artist 1 in the first 6 songs played
and let Y2 be the number of songs from Artist 2 in the first 6
songs played.
(a) Find the joint probability distribution function for Y1 and
Y2.

This is my dataset
Find mean, median, mode, variance, standard deviation,
coefficient of variation, range, 70th percentile,
3rdquartile of the data and skewness and define what
each of these statistics measure. For example, mean is a measure of
the central tendency, what about the rest?
