Ben, Max, and Yolanda are at the front of three separate lines in the cafeteria waiting to be served. The serving times for the three lines follow independent Poisson processes with respective parameters 1, 2, and 3. (a) Find the probability that Yolanda is served first.
(b) Find the probability that Ben is served before Yolanda.
(c) Find the expected waiting time for the first person served.

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

step-by-step explanation:

what do you mean by "representation"? graph? table? etc.

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions
