They each have a 1/100 chance hypothetically. The chance they both pick it would be 1/100 ×1/100= 1/10000
That ratio will be 15/10 = 1.5.
Check:
.. 22.5/15 = 1.5
.. 33.75/22.5 = 1.5
So I estimated to 110. And I got 50 rock songs and 60 dance songs. I used the ratio 5:6. Hope this helps you.
Answer:

so 2/7
Answer:

y = x^2 + 8x + (8/2)^2 - 3 - (8/2)^2
y = x^2 + 8x + 16 - 3 - 16
