Answer:
0.619 = 61.9% probability of choosing a professor or an instructor.
Step-by-step explanation:
A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this question, we have that:
7 + 4 + 4 + 6 = 21 members
7 + 6 = 13 professors or instructors.
Find the probability of choosing a professor or an instructor.
p = 13/21 = 0.619
0.619 = 61.9% probability of choosing a professor or an instructor.

Answer:
50,803,200 ways
Step-by-step explanation:
In this situation, since you should alternate girl-boy or boy-girl, the line-up can either start with a boy or a girl kicking which would yield one of the two following patterns:
BGBGBGBGBGBGBG or GBGBGBGBGBGBGB.
For each of those patterns, there are 7! ways to arrange all boys and 7! ways to arrange all girls. The number of ways that a line-up can be made for one round of kicking is:
![n=2*7!*7!\\n=2*(7*6*5*4*3*2)^2\\n=50,803,200\ ways](https://tex.z-dn.net/?f=n%3D2%2A7%21%2A7%21%5C%5Cn%3D2%2A%287%2A6%2A5%2A4%2A3%2A2%29%5E2%5C%5Cn%3D50%2C803%2C200%5C%20ways)
There are 50,803,200 ways to set the line-up.
Step-by-step explanation:
Price after discount = 122.80
Discount = 40.94
So, amount before discount = 122.80 + 40.94 = 163.74
=
x 10
= ![\frac{40.94}{163.74} (100)](https://tex.z-dn.net/?f=%5Cfrac%7B40.94%7D%7B163.74%7D%20%20%28100%29)
= 0.25
= 0.25 x 100
= 25%
