Answer:
0.2601
Step-by-step explanation:
There are 19C16 = 969 ways for Lester to choose 16 of the 19 objects.
There are 12C11 = 12 ways to choose 11 vases, and 7C5 = 21 ways to choose a non-vase, for a total of (12)(21) = 252 ways to choose exactly 11 vases in 16 objects.
So, the probability of interest is ...
252/969 ≈ 0.2601
_____
nCk = n!/(k!(n-k)!) ... the number of ways to choose k objects from n

Well, okay then. I'll consult you if I ever need help. Thanks friend. xx
12, 13, 15, 17, 17, 20 are the numbers in order
The median (middle number) would be 15 and 17
If there are 2 medians, you need to add both of them and divide by 2
15 + 17 = 32
32/2 = 16
So the median is 16
