By collecting like terms we have:
★ EXPONENTIALLY RESOLVED ★
(5/4)^3
= 5 ( 5 ) ( 5 ) / 4 ( 4 ) (4 )
= 25 ( 5 ) / 16 ( 4 )
= 125 / 64

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
6 subsets are possible, but the number of subsets depends on the problem
The population density of Romania in 1997 given its area and the population is 95 people per square km.
<h3>What is the population density?</h3>
Population density is the number of people that live in a square kilometer of an area. It is determined by dividing total population by total area.
Population density = population / area
22.600,000 / 237301 = 95 people per square km
