Answer:
Total number of CDs= 10+5+12+3=30
Number of jazz CD= 3
Total number of outcomes that Kyle will select a jazz CD from the box= 3C1= 3!/1!2!= 3
Total number of outcomes for any CD = 30C1 = 30!/1$29! =30
Hence, the probability of picking jazz CD =3/30 = 1/10 0.1
Now since, one CD is out, the total number of CD left = 29
No. of country CD= 10
Total number of outcomes that Kyle will select a country CD from the box= 10C1= 10!/1!9!= 10
Total number of outcomes for any CD(one is out) = 29C1 = 29!/1$28! =29
Hence, the probability of picking country CD =10/29 = 0.344827
