A flower vase has 5 white lilies, 4 pink roses, and 6 yellow carnations. One flower is chosen at random and given to a woman for her to keep. Another flower is then chosen at random and given to a different woman for her to keep. Both women received a pink rose. Are these events independent or dependent?

I think it's dependant....

Rose is correct

 

The probability that the  second woman receives a pink rose is dependent upon what the first woman receives

 

If the first woman does not receive a pink rose....the probabilty of the second woman receiving one is 4/ 14 2 / 7

 

It the first woman does receive a pink rose....the probability of the second woman receiving one is  3 / 14
