A bag contains 6 green marbles and 5 white marbles. You select a marble at random. What are the odds in favor of picking a green marble?
There are a total of 6 + 5 = 11 marbles in the bag.
The odds in favor of picking a green marble are the number of desired outcomes (picking a green marble) divided by the number of total possible outcomes.
Number of desired outcomes = 6 (there are 6 green marbles)
Number of total possible outcomes = 11 (there are 11 marbles in total)
Odds in favor of picking a green marble = 6/11
