The order in which the CDs are chosen is not important. So we use the combinations formula to solve this question.
1 Bach CD, from a set of 4.
1 Beethoven CD, from a set of 6.
1 Brahms CD, from a set of 3.
1 Handel CD, from a set of 2.
So, D=144
4 CDs from a set of 4+6+3+2 = 15.
So, T= 1365
p= D/T= 144/1365 = 0.1055
10.55% probability that she will choose one by each composer
Chord because the radius is the center of the circle to a side and diameter is the length across a circle through the center point so chord is the correct answer! I hope this helps! :)
Answer:
<em>4</em>
Step-by-step explanation:

Square root is the opposite operation of squaring. You are looking for a number that when you square it (multiply the number by itself) you get 16.
That number is 4 since 4 * 4 = 4^2 = 16

Answer: 15
Step-by-step explanation: 2 minus negative 1 is the same as 2+1. 2 plus 1 is 3 and 5 times 3 is 15. Therefore, 15 is your answer.
