Aradio disc jockey has 8 songs on this upcoming hour's playlist: 2 are rock songs, 3 are reggae songs, and 3 are country songs. the disc jokcey randomly chooses the first song to play, and then she randomly chooses the second song from the remaining ones. what is the probability that the first song is a rock song and the second is a country song?

P(the first song is a rock song and the second is a country song)=2/8×3/7=6/56=3/28

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
