A rack of 15 billiard balls is shown. If one ball is selected at​ random, determine the odds against it containing a number grea
andre [41]

Using the probability and odds concepts, it is found that the odds against it containing a number greater than or equal to 7 is \frac{2}{3}.

  • A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.
  • An odd is the <u>number of desired outcomes divided by the number of non-desired outcomes</u>.

In the rack, there are 15 balls, numbered from 1 to 15. Of those, <u>6 are less than 7</u>(against it containing a number greater than or equal to 7 is equivalent to it containing a number less than 7), thus:

  • There are 6 desired outcomes.
  • There are 9 non-desired outcomes.

The odd is:

\frac{6}{9} = \frac{2}{3}

The odds against it containing a number greater than or equal to 7 is \frac{2}{3}.
