Answers
First you have to define perimeters of Binomial distribution.
n - how many trials/questions do you have p - probability guessing right answer to each question x - how many successes do you expect. Assuming the 6 questions are independent, n=6 (questions) p=probability of guessing the right answer (1/5) x=exactly the number of successes over the 6 questions (2).
Look up the appendix table, or the Excel function to calculate the probability.
