Answer:
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 )
= 
= 
 = 
= 
= .0546

Hi!
3x - 30 = x + 10
<h3>Solve by isolating x on one side. </h3><h3>Add 30 to both sides. </h3>
3x - 30 + 30 = x + 10 + 30
3x = x + 40
<h3>Subtract x from both sides. </h3>
3x - x = x - x + 40
2x = 40
<h3>Divide by 2 on both sides</h3>
2x/2 = 40/2
<u>x = 20</u>
<h2>The answer is x = 20</h2>
Hope this helps! :)
