A bag contains 3 green marbles and 8 white marbles. Suppose a marble is randomly selected. What are the odds in favor of picking a white marble?

Respuesta :

To work out this, you must first find out exactly how many marbles there are:

8+3 = 11

Since 8 of the 11 balls are white marbles, then the odds of selecting a white marble are 8/11.
