Answer:
Probability that they are the youngest is 0.000549
Step-by-step explanation:
Given
Number of students = 16
Selected students = 4
Let n = number of students
n = 16
Let r = selections
r = 4
We're interested in selecting 4 students out of 16; the keyword, selection means we're dealing with combination because order is not important.
So,
Solving for nCr
nCr = n!/((n-r)!r!)
16C4 = 16!/((16-4)!4!)
16C4 = 16!/(12!4!)
16C4 = 16 * 15 * 14 * 13 * 12!/(12!4!)
16C4 = 16 * 15 * 14 * 13 / 4 * 3 * 2 * 1
16C4 = 1820 ways
There are 1820 ways of selecting 4 students from a total of 1820.
Only one of these ways can the four of them be the youngest.
So, probability = 1/1820
Probability = 0.0005494506
Probability that they are the youngest is 0.000549 (approximately)
Answer:
The equation relating the number of cars to the number of passengers is p = 4n
Step-by-step explanation:
Given that certain type of car has room for 4 passengers
To find: write an equation relating the number of cars to the number of passengers
Let "n" be the number of cars
Let "p" be the number of passengers
From given information,
Car has room for 4 passengers. Therefore, we can frame,
number of passengers = 4 ( number of cars )
p = 4 (n)
p = 4n
Thus the equation relating the number of cars to the number of passengers is p = 4n
Answer:
25$
Step-by-step explanation:
If 4 stickers cost 2$, then each sticker would cost .50$
