Answer:
Step-by-step explanation:
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 probability that none of the 8 guessed correctly is
4/5×4/5×4/5×4/5×4/5×4/5×4/5×4/5
=(4/5)^8
=0.16777216
There are eight cities on the list.
The number of groups of 2 is (8·7)/2 = 28
The number of groups of 3 is (8·7·6)/(3!) = 56
The number of groups of 4 is (8·7·6·5)/(4!) = 70
The number of groups of 5 is (8·7·6·5·4)/(5!) = 56
The number of groups of 6 is (8·7·6·5·4·3)/(6!) = 28
The number of groups of 7 is (8·7·6·5·4·3·2)/(7!) = 8
So there are (28+56+70+56+28+8) = 246 ways to visit "some" of them.
There's only one way to visit "all" of them, and
there's only one way to visit "none" of them.
So, all together, Louise has 248 travel options.
If she decides to visit Chicago, I will show her a good time.
