NEED HELP Wan has 22 bulbs of the same shape and size in a box. The colors and amounts of the bulbs are shown below:

6 blue bulbs

9 red bulbs

7 orange bulbs

Without looking in the box, Wan takes out a bulb at random. He then replaces the bulb and takes out another bulb from the box. What is the probability that Wan takes out an orange bulb in both draws?

7 over 22 multiplied by 7 over 22 equal 49 over 484

7 over 22 multiplied by 6 over 21 equal 42 over 462

7 over 22 plus 6 over 21 equal 279 over 462

7 over 22 plus 7 over 22 equal 308 over 484
