Kylie works at a local music store. The store receives a shipment of new CDs in a box. In the shipment, there are 10 country CDs, 5 rock CDs, 12 hip hop CDs, and 3 jazz CDs. What is the probability that the first CD that Kylie pulls from the box will NOT be hip hop?

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

Step-by-step explanation:

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
