The probability that she will choose one by each composer is 2/455.
<h3>What is the probability?</h3>
Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
Probability = (number of bach cds / total number of cds) x (number of beethoven cds / total number of cds - 1) x (number of Brahms cds / total number of cds-2) x (number of Handel's cds / total number of cds-3)
= 4/15 x 6/14 x 3/13 x 2/12 = 2/455

Answer:
65/4 or 16.25
Step-by-step explanation:
Because a=8 b=4 c=16, so this equation would be:
c^2/b^2+b^2/a^2
= 16^2 / 4^2 + 4^2 / 8^2
= 256 / 16 + 16 / 64
Times 256/16 by 4 and you would get:
= 1024 / 64 + 16/64
= 1040 / 64
Divide both side by 8, we got:
130/8
Divide both side by 2, we got:
65/4 or 16.25
