To find the probability of selecting two carnations out of the total flowers, we first need to find the total number of ways to choose 2 flowers out of the 18 total flowers in the vase.
Total number of ways to choose 2 flowers out of 18 flowers = 18C2 = (18*17)/(2*1) = 153 ways
Next, we need to find the number of ways to choose 2 carnations out of the 6 carnations in the vase.
Number of ways to choose 2 carnations out of 6 = 6C2 = (6*5)/(2*1) = 15 ways
Therefore, the probability of selecting 2 carnations out of the total flowers is:
Probability = Number of ways to choose 2 carnations / Total number of ways to choose 2 flowers
Probability = 15 / 153
Probability = 5 / 51
So, the probability of selecting two carnations is 5/51.
