Answer:
Step-by-step explanation:
Given that the random variable x represents the number of phone calls an author receives in a day
Poisson distribution is a discrete distribution with random variable countable.
Here no of calls cannot be in fraction or decimal.
Also given that X is Poisson with mean = 7.6
X is discrete since no of phone calls can take values as 1,2,3....
X can take any value from 0 to infinity.
x=3.2 is not possible since 3.2 calls does not exist.

Currently 100 students can eat for 20 days, so we need to find the number of days 125 students can eat.
Originally:
100 students eat for 20 days
New:
125 students eat for x days. Multiply original number of students by original number of days which will give the total amount of students per day. Then divide the total amount of students per day by the new number of students to find the new number of days.
x= (100 students * 20 days)/ (100+25)
x= (100 * 20)/ 125
x= 2000/125
x= 16 days
ANSWER: 125 students can eat for 16 days.
Hope this helps! :)
