wan has 22 bulbs of the same shape and size in a box. the colors of 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
a or b? i know he replaced it in the first one, but did he replace it in the second?
