Answer:
P43=4!(4–3)!=241=24
Step-by-step explanation:
There are four choices you can make for the lead reindeer. For each possible choice, there are then three remaining you can choose to fly second, making 4×3=12 choices for the lead pair. For each possible choice there are two remaining reindeer to take up the back position, making 12×2=24 choices for the team of three.
This type of problem is called a permutation problem, and we write Pnr for the number of ways of choosing r items from n possibilities when the order of the items matters. In this case we are choosing 3 reindeer from 4 possibilities, and the order they appear in the flying line does matter, so the answer we want is P43. The general formula is Pnr=n!(n−r)!. For the answer we are looking for we therefore have:
P43=4!(4–3)!=241=24
Its mean 130000÷12

Answer:
38.46%
Step-by-step explanation:
Given,
The total number of students = 325
The number of students preferred pineapples = 200
Therefore, The number of students preferred bananas = (325 - 200) = 125
Among 325 students, banana is preferred 125 students
Among 1 student, banana is preferred 125/325 students
Among 100 students, banana is preferred (125*100)/325 students
= 500/13
= 38.46% (2 decimal places)
