The probability that they sit next to each other is 50%.
Step-by-step explanation:
Consider the provided information.
It is given that there are four seats within the row are first come, first served during boarding.
There are 4 seats and 2 customers (Karen and Georgia)
The total number of ways in which Karen and Georgia can sit is: 
Now if they will sit together, then consider Karen and Georgia as a single unit.
Thus, the number of ways in which they can sit together is: 
The required probability is:

Hence, the probability that they sit next to each other is 50%.
Answer:
Step-by-step explanation:
f(-2)= 4(-2)^2 + 3 = 4(4) + 3 = 16 + 3 = 19
g(19) = 3(19) + 2 = 57 + 2 = 59
g(-2)= 3(-2) + 2 = -6 + 2 = -4
f(-4)= 4(-4)^2 + 3 = 64 + 3 = 67
