The probability that the student does not know the answer but he randomly guesses it is 0.146025
<h3>How to solve for the probability of having a correct guess</h3>
The question has only one right answer out of 5 choices.
Probability he answers incorrectly:
1 - 0.55 * 4/5
= 0.45 * 0.8
= 0.36
Probability he does not know answer but answers the question correctly
![\frac{(1-0.55)\frac{1}{5} }{0.55+(1-0.55)\frac{1}{5} }](https://tex.z-dn.net/?f=%5Cfrac%7B%281-0.55%29%5Cfrac%7B1%7D%7B5%7D%20%7D%7B0.55%2B%281-0.55%29%5Cfrac%7B1%7D%7B5%7D%20%7D)
= 0.09/0.55+0.09
= 0.140625

Answer:
-16/3 = x
Step-by-step explanation:
3(x – 2) + 4x = 10(x + 1)
Distribute
3x -6 +4x = 10x+10
Combine like terms
7x-6 = 10x+10
Subtract 7x from each side
-6 = 3x+10
Subtract 10 from each side
-16 = 3x
Divide by 3
-16/3 = 3x/3
-16/3 = x
