As in Exercise 2.1 and Example 3.11, a song is chosen at random from a person's mp3
Question:
Let A be the event that a song is either blues, jazz, or rock, i.e.,
A = {x | x is a blues, jazz, or rock, song},
When one song is chosen at random. Let B, J, R denote the events that the song is a blues, jazz, or rock song, respectively.
Find P(B | A) and P(J | A) and P(R | A). Since B, J, R are disjoint and A = B U J U R, these three answers should sum to 1.
