There are 25 students. Four of these students are selected to attend four different conferences. The first student selected will go to a conference in Makati city, the second will go to Paranaque city, the third to Quezon city and the fourth to Caloocan city. How

many such selections are possible?

256

12,650

303,600

390,625

the number of possible selection is 12650

Option b) 12650  is the correct answer.

Step-by-step explanation:

Given the data in the question;

total number of students n = 25

number of student selected r = 4

= ²⁵C₄

= 25! / ( 4!( 25 - 4 )! )

= 25! / (4!(21)!)

=  12650

Therefore, the number of possible selection is 12650

Option b) 12650  is the correct answer.

after simplifying it i got: -36.25 as my answer. hope that !

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
