1. If the school asked you to select 4 places among you suggested and one
of them must be amusement park. In how many ways can you select
Answers & Comments
Assuming there are 6 suggested destinations including one amusement park, the number of ways to select 4 places with one of them being an amusement park can be found using combinations.
We can select the amusement park in 1 way and the remaining 3 places from the remaining 5 non-amusement park places in 5 choose 3 ways.
Therefore, the total number of ways to select 4 places with one of them being an amusement park is:
1 x (5 choose 3) = 1 x 10 = 10
So, there are 10 ways to select 4 places with one of them being an amusement park.
