Given information
More than 96% of the 15000 or so universities offer online courses. Out of this, a random sample of 13 universities is chosen and surveyed for whether they have online courses.
The random variable X representing the number of universities that offer online courses among the sample of 13 chosen universities follows a binomial distribution with n=13 and p=0.96.
Step-by-step explanation
Step 1.
The required probability is expressed as 
and can be found using the binomcdf function in the calculator.
Since n=10, p=0.96 and number of successes x=10, input binomcdf(13,0.96,10) in the calculator to get the answer which is 0.01354.
