why you are so confused????

Question 2:
a) If the five numbers cards 1,2,3,4,5 are put into a box, in how many different
a) ways could you draw one out?
Ans:
= 5 x 4 x 3 x 2 x 1
= 5!
= 120
b) When one of them has been drawn, in how many ways could you
a) draw a second?
Ans:
5 P 2 = 5! / (5 - 2)! = 120/2 = 60
c) Therefore, in how many ways could you draw two numbers?
Ans:
2! = 2 x 1
2! =2
d) What is the meaning of the symbol 5P4?
Ans:
The number of permutations of 5 different things taken 4 at a time.
e) Evaluate 5P4
Ans:
n P r = n! / (n - r)!
5 P 4 = 5! / (5 - 4)!
5 P 4 = 5 x 4 x 3 x 2 x 1 / 1!
5 P 4 = 120”

the above 2 q answer is wrong par D and E is correct

2nd question Part A-B-C showing wrong calculation

5 P 2 = 5! / (5 - 2)! = 120/2 = 60  

is there any mistake

please guide me if i am wrong ???????

5-2=3 

3!=3 x 2 x 1 

=6

nd then

i think so this(120/2 = 60) must be

120/6=20


thats my again question

5p2

5!/(5-2)!
5!/(3!)
=120/60=answer 20 its correct

yesh even i think there was a mistake
i did the as uh did
Answer=20
