Answer:
0.3523 is the probability that the student will get less than 10 but more than 7 questions right.
Step-by-step explanation:
We are given the following information:
We treat answering the question correctly as a success.
P(guess of answer is correct) = 50% = 0.5
Then the number of questions follows a binomial distribution, where
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 18
We have to evaluate:
0.3523 is the probability that the student will get less than 10 but more than 7 questions right.
