Step-by-step explanation:
The total number of seats in a row = 5
Lets suppose you are standing in front of the row, so you have 3 seats on one side of you then the passage of the plane and 2 seats on the other side. Out of 3 seats, 1 is window, 1 is middle and 1 is aisle. Similarly, out of the 2 seats on the other side, 1 is the window and 1 is aisle seat, Hence, a total of 5 seats.
As 2 friends have requested to be seated in the same row. So probability of them getting aisle seats becomes 2/5 for 1st friend (as there are 2 aisle seats out of 5 seats) and 1/4 (1 seat is already allocated to the friend so only 1 aisle seat is left out of 4 seats) for the second one.
So, joint probability becomes = ![\frac{2}{5}*\frac{1}{4}= \frac{1}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D%2A%5Cfrac%7B1%7D%7B4%7D%3D%20%5Cfrac%7B1%7D%7B10%7D)
or probability becomes 0.1

Answer:
2
Step-by-step explanation:
When a circle is colored it means the point is included in a graph but when a circle is not colored the point is not included. So, for x value 5 the y value is 2.
I don't know much about this but as far as I can tell the mean is about 8, that would make the deviation value of about 2
