A quiz consists of 10 true or false questions. To pass the quiz a student must answer at least eight questions correctly.
If the student guesses on each question, what is the probability that the student will pass the quiz?

The probability of  the student will pass the quiz = .0546

Step-by-step explanation:

Given -

Total no of question = 10

If the student guesses on each question there are two outcomes true of false

the probability  of guesses  question correctly =  

the probability  of success is (p) =  

the probability  of guesses  question incorrectly =

the probability  of failure is (q) = 1- p =

If the student guesses on each question he must answered at least 8 question correctly

the probability of  the student will pass the quiz =

= P(X = 8 ) + P(X = 9) + P(X = 10 )
