Suppose that a box containing music CDs has 4 with country music, 6 with rock music, 3 with jazz music, and 7 with rap music. If one CD is selected at random from the box, determine the probability that
a. The CD has rap music.
b.The CD has jazz music.
c. The CD does not have jazz music.
d.The CD has classical music.
A box containing music CDs has 4 with country music, 6 with rock music, 3 with jazz music, and 7 with rap music.
Total = 4+6+3+7=20 musics
a) A rap music can be selected in 7 ways from 20 musics
So probability of picking one rap music is = 7/20
b) A jazz music can be selected in 3 ways from 20 musics
