Answer:

Yes, this is a Binomial distribution, and the number of trials is 10.

Step-by-step explanation:

From the given information:

We are being told that ten students are chosen from a statistics class of 22 students.

If X represents the random variable for the number of students who got an "A" in the class.

Then we have two possible outcomes;

Number of students that got an "A" = (Success)

Number of students that did not get an "A" = (Failure)

Thus,  this is a Binomial distribution because it consists of two outcomes, and the number of trials is 10.
