Now that weddings can be held again you end up being invited to one and you decide to observe the musical taste of the guests. Having observed previous weddings we can assume that each person asks for a dance track with a probability of 0.2, a pop song with a probability of 0.3, a rock song with a probability of 0.15, or a hip hop song with a probability of 0.35. Assume each guest makes one request and all of their requests are made independently.
