Answer:

0.072 = 7.2%

Step-by-step explanation:

probability that Ms. Florina will select a blue rubber band:

We have 18 blue of a total of 50, so probability = 18/50 = 0.36

probability that Ms. Florina will select a green rubber band:

We have 10 blue of a total of 50, so probability = 10/50 = 0.2

The probability that she will select a blue rubber band, return it to the bag,

and then select a green rubber band:

We just need to find the product of the probabilities above:

Probability = 0.36 * 0.2 = 0.072 = 7.2%
