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

We know that
[surface area <span>of the ramp]=10*16+8*16+6*16+2*[6*8/2]
</span>[surface area of the ramp]=160+128+96+48-----> 432 ft²
the answer Part a) is
the surface area of the ramp is 432 ft²
if 1 ft² is sold for--------------------> $3
432 ft²-------------------> x
x=432*3-----> x=$1296
the answer Part b) is
$1296
