Chen plans on listening to 360 songs, and if she has 444 <span>classical songs, 333 rock songs, and 222 rap songs, the ratio of the songs she have would be 4:3:2. We can add 4,3, and 2 to get 9. 360/9=40.Now, we do 40*4 to get 160.
Chen will be listening to 160 songs.</span>
Using the principle of probability, the likelihood that Shreya wins by getting <em>2 blues and 1 red</em> is 0.416

Creating an area model or tree diagram for the third spinner would result in a sample space of (48 × 12) = 576 combinations.
However, the probability that Shreya would win can be obtained thus :
<u>To win he needs to pick get 2 blues and 1 red</u> in any order :
3! = 3 × 2 × 1 = 6 ways
P(BBR) = 1/3 × 4/8 × 5/12 = 0.0694444
P(winning) = 6 × 0.0694444 = 0.416
Therefore, the probability that Shreya wins is 0.416.
