Question 358274
<pre>
The probability that a person answered incorrectly is {{{4/5}}}
P(1st answered incorrectly AND 2nd answered incorrectly AND 
3rd answered incorrectly AND 4th answered incorrectly AND 
5th answered incorrectly AND 6th answered incorrectly AND 
7th answered incorrectly AND 8th answered incorrectly)

Since "AND" mean to multiply, the above probability is
{{{4/5}}}{{{""*""}}}{{{4/5}}}{{{""*""}}}{{{4/5}}}{{{""*""}}}{{{4/5}}}{{{""*""}}}{{{4/5}}}{{{""*""}}}{{{4/5}}}{{{""*""}}}{{{4/5}}}{{{""*""}}}{{{4/5}}}

or {{{(4/5)^8}}}{{{""=""}}}{{{65536/390625}}} or about .16777216
