Here we have to find the probability
. Now express the probability in terms of standard normal cumulative distribution function. That is
.

Now you can look up the probability from the standard normal tables. Its value is

20L = 20,000mL. 20,000 / (22+3) people = 800mL/person
Integers because it uses degrees
So I'm not totally sure but I got -15.32
So sorry if it's wrong!!
