Question -
Answer -
In this question, wehave the repeated correct answer guessing form the given multiple choicequestions are Bernoulli trials
Let us now assume, Xrepresents the number of correct answers by guessing in the multiple choice set
Now, probability ofgetting a correct answer,┬аp = 1/3
Thus, q = 1 тАУ p = 1 тАУ1/3 = 2/3
Clearly, we have X isa binomial distribution where n = 5 and┬аP = 1/3
