Problem 95b

Given information

From the previous task of this question, it is known that the random variable X represents the number of universities which offer online courses out of the 13 chosen universities in the sample.

Step-by-step explanation

Since X represents the number of universities which offer online courses from the chosen sample of 13 universities, it follows that X can take on integer values from 0 to 13.

In other words, the permissible values of X are: {0,1,2,3,4,5,6,7,8,9,10,11,12,13}
