What is the probability of 3 students out of 11 getting the same grade on an exam?
It is not possible to answer the question since there is no information on how many grades there are. Second, the probability of a student getting a particular grade will depend on how "wide" the grade is: some grade boundaries are closer together than others. Furthermore, the grades achieved by the students are not independent events. If the exam is very easy, they might all get a top grade.

How can you find the grade average from 5 wrong out of 20?
You got 75% correct.Reason:5 is 1/4 of 20, therefore meaning that you got 3/4 correct. And of course 3/4 = .75, or 75%

What would 2 f's 3 a's 2 c's and 2 d's average out to be on ur best estimate?
Do you mean like report card grades, like your Grade Point Average (GPA)? If you do then your GPA would be a 2, which is a letter grade average of a C. The GPA is calculated by giving a point value to each letter grade. Then you add up the points and divide by the number of letter grades. The maximun GPA is 4.0, so if you get any higher you did it wrong(it's happened to me, that's how I know). The point values are as follows: ***A = 4.0 ***B- = 2.7 ***D+= 1.3 ***A- = 3.7 ***C+= 2.3 ***D= 1.0 ***B+= 3.3 ***C= 2.0 ***D-= .70 ***B = 3.0 ***C-= 1.7 ***F = 0 Once you divide whatever number you get, look for it here. That is your letter grade average. If the number is not here, just round. Hope I helped :)
