Suppose you just purchased a digital music player and have put 8 tracks on it. after listening to them you decide that you like 4 of the songs. with the random feature on your player each of the 8 songs is played once in random order. find the probability that among the first two songs played
(a) you like both of them. would this be unusual?
(b) you like neither of them
(c) you like exactly one of them.
(d) redo () if a song can be replayed before all 8 songs are played.
(a) the probability that you like both songs is (round to three decimal places as needed)
would this be unusual for you to like both songs yes or no
(b) the probability that you like neither songs is (round to three decimal places as needed)
(c) the probability that you like exactly one song is (round to three decimal places as needed)

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
