12 red + 16 blue + 18 white = 46 marbles

9. 3 marbles NO replacement: no white?
28/46 x 27/45 x 26/44
0.61 x 0.6 x 0.59 is about 22%

Each time we pick a red or blue we have one less to choose from next time

10. 4 marbles WITH replacement: all white?
18/46 x 18/46 x 18/46 x 18/46
0.39 x 0.39 x 0.39 x 0.39 is about 2%

11. 2 marbles NO replacement: red then blue

12/46 x 16/45
12 x 45 / 16 x 46
540/736
135/184 :)

If 1/a + 1/b =1/c and ab=c,what is the average of a and b?
goblinko [34]
If we solve the left side of the given equation,
                                  1/a + 1/b = 1/c
 we get an answer of,
                                    b+a / ab = 1/c
Since ab = c, we can conclude that b + a is 1. The average of these two numbers is equal to there sum divided by 2. The answer is therefore equal to 0.5.

The world's population is expected to grow at a rate of 1.3% per year until at least the year 2020. In 1994 the total population
Marina CMI [18]
The solution to your problem is as follows:

Given: 
P₀ = 5,642×10^6 people, 
i = 1.3% = 0.013 per year, 
n = 2020 - 1994 = 26 years, 

We get: 
<span>
Pn = P₀ e^(i.n) </span>
. . .= 5,642×10^6×e^(0.013×26) 
<span>. . .= 7,911×10^6 people

Therefore, the </span>the world's predicted population in the year 2020 is <span>7,911×10^6 people.
