.
Step-by-step explanation:
From the given information it is clear that:
Democrats = 8
Republicans = 5
Independents = 5
Total number of member in the group is

We need to find the probability of selecting two Independents.
According to binomial distribution the total number of ways to select r items form n items is

Total number of ways to select 2 members from 18 members is

Total number of ways to select 2 members from 5 Independents is

The probability of selecting two Independents is


Therefore the probability of selecting two Independents is
.

Answer:
The line segment 7 cm long is shown below.
Step-by-step explanation:
First we draw a line line segment whose length is 7 cm long. Then we divide the line in small parts.
The length of each part is 1 cm.
Six points on the line segment divides the line in 7 equal parts and length of each part is 1 cm.
From the figure it is noticed that we have total 7 small parts and length of each part is 1 cm. So length of 7 parts is

Hence the total length of line is 7 cm.
