Question

Mr. Jones got four seats on the school's trip to Grand

Canyon for his students. In how many different ways Mr.
Jones can select a group of four from his class of 36?

Answer 1

D. 58,905

Explanation:

Number of seats available for Mr. Jones had for the trip = 4

Number of students in his class = 36

Number of ways he can select a group of 4 out of 36 students from his class is calculated as follows:

`C \binom{36}{4} = (36!)/((36 - 4)! * 4!))`

`= (36!)/((32! * 4!)) = 58,905`
