Question

a jar contains three marbles; 1 yellow (y), 1 orange (o), and 1 red (r). which list shows all the possible outcomes for choosing two marbles at random from the jar if the first marble is replaced after it is drawn? how many of the outcomes contain at least one yellow marble? 2 3 4 5

Explanation:

Step1: List all possible outcomes

Since the first - marble is replaced, for the first draw and the second draw, there are 3 choices each time. The possible outcomes are (y,y), (y,o), (y,r), (o,y), (o,o), (o,r), (r,y), (r,o), (r,r).

Step2: Count outcomes with at least one yellow

Count the number of outcomes that contain at least one yellow marble. The outcomes are (y,y), (y,o), (y,r), (o,y), (r,y). There are 5 such outcomes.

Answer:

5
