Answer:
$16.6
Step-by-step explanation:
x is the price of each CD before tax
so 3x + 3.60 = 53.40
3x = 53.40 - 3.60 = 49.80
x = 49.80/3 = 16.6

Answer:
30% probability that the ball taken from B is red.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
Red ball from urn A:
3/6 = 1/2 probability of getting a red ball from urn A.
Then urn B will have 5 balls, 2 of which are red, so 2/5 probability of getting a red ball.
Blue ball from urn A:
3/6 = 1/2 probability of getting a blue ball from urn A.
Then urn B will have 5 balls, 1 of which is red, so 1/5 probability of getting a red ball.
Total:
![p = \frac{1}{2}*\frac{2}{5} + \frac{1}{2}*\frac{1}{5} = \frac{2}{10} + \frac{1}{10} = \frac{3}{10}](https://tex.z-dn.net/?f=p%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2A%5Cfrac%7B2%7D%7B5%7D%20%2B%20%5Cfrac%7B1%7D%7B2%7D%2A%5Cfrac%7B1%7D%7B5%7D%20%3D%20%5Cfrac%7B2%7D%7B10%7D%20%2B%20%5Cfrac%7B1%7D%7B10%7D%20%3D%20%5Cfrac%7B3%7D%7B10%7D)
3/10 = 0.3 = 30%.
30% probability that the ball taken from B is red.
