8. There are 10 balls in a bag numbered from 1 to 10. Three balls are selected at random without replacement.
PIT_PIT [208]

Answer:

a. 720

b. 0.3

Step-by-step explanation:

a.

Three balls are selected at random without replacement.

First ball can be selected in 10 ways

Second ball can be selected in 9 ways

Third ball can be selected in 8 ways

Thus, there are 10×9×8 =720 different ways of selecting three balls.

b.

There are three cases that satisfy this condition

  1. first ball picked is 5, the others are not
  2. first ball is not 5, second is 5, third is not
  3. first and second ball is not five, third ball is 5

Each probabilities are:

  1. \frac{1}{10} * \frac{9}{9} *\frac{8}{8} =\frac{1}{10}
  2. \frac{9}{10} *\frac{1}{9} *\frac{8}{8} =\frac{1}{10}
  3. \frac{9}{10} *\frac{8}{9} *\frac{1}{8} =\frac{1}{10}

Thus, one of the balls selected is the number 5 is then \frac{1}{10} + \frac{1}{10} + \frac{1}{10} = \frac{3}{10}

If 200 vitamines cost $8.75, what should 500 vitamins cost?
WARRIOR [948]
Hello!  So, the problem is saying that 200 vitamins cost $8.75, and that is what we know.  We also know that we're going to be looking at the cost of 500 vitamins, but we don't know.  The numbers presented can be put into a proportion, and that can help solve the problem.  200 to 8.75, and 500 to a number we don't know.  I'm no sure if you familiar with the how to set up a proportion, but it's saying this number over this other number (which is a fraction) equals another fraction.  Make sure that your numbers always match up, so your not saying vitamins over money equal money over vitamins.  Use cross products, divide, and then you'll have your answer.  For this problem, since yours solving for money, make sure to have two decimal points and a dollar sign.  I hoped this helped, if you have any questions shoot me a question or message.  Good luck!
