A bag contains 9 green marbles and 7 white marbles. You select a marble at random. What are the odds in favor of picking a green marble?

1 answer

There are a total of 9 + 7 = 16 marbles in the bag.
The odds in favor of picking a green marble are the number of favorable outcomes (picking a green marble) divided by the number of total outcomes. This can be expressed as a fraction or a ratio.
Fraction: Number of green marbles / Total number of marbles = 9/16
Ratio: Number of green marbles : Number of non-green marbles = 9:7
Therefore, the odds in favor of picking a green marble are 9:7 or 9/16.
