-
- acc to formula (n+r-1)C (r-1) = (6+5-1)C(5-1)
=10C4 = 210 answer - 10 years agoHelpfull: Yes(58) No(2)
- For A , there are 6 ways
For B, there are 5 ways
Like that 6 * 5 * 4 * 3 * 2 = 720 ways
Ans : 720 ways - 10 years agoHelpfull: Yes(45) No(47)
- If one of them gets all toffees => 5C1 = 5ways
If 6 toffees divided among two(1+5,2+4,3+3,4+2,5+1) => 5C2*5 = 50 ways
If 6 toffees divided among three(10 ways.1,2,3 1,4,1 2,2,2)=> 5C3*10=100 ways
If 6 toffees divided among four(10ways .1,2,2,1 3,1,1,1 ) => 5C4*10 = 50 ways.
If 6 divided among all(5 ways) => 5ways.
Total no. of ways = 5+50+100+50+5=210ways. - 10 years agoHelpfull: Yes(14) No(0)

- In 6c5 ways = 6 ways
- 10 years agoHelpfull: Yes(6) No(9)
- A, B,C,D,E
first 6 can be distributed among them in 6c5 ways..suppose it is given to A..
then remaing 5 can be distributed to B,C,D,E in 5c4 ways(to B)
4 can distributed among C,D,E in 4c3 ways (to C)
3 can be distributed b/w D,E in 3c2 ways (to D)
Remaing 2 will be give to E
i.e: 6c5 * 5c4 *4c3 * 3c2 * 2c1
6 * 5 * 4 * 3 * 2 * 1 = 720
Ans : 720

- 720 seems wrong.
As per the question,toffees arent different but people are.So toffees need not have arrangement.
If one of them gets all toffees => 6C1 = 6 ways
If 6 toffees divided among two(1+5,2+4,3+3,4+2,5+1) => 6C2*5 = 75 ways
If 6 toffees divided among three(10 ways)=> 6C2*10=150 ways
If 6 toffees divided among four(10 ways) => 6C4*10 = 150 ways.
If 6 divided among all(5 ways) => 6C5*5=30 ways.
Total no. of ways = 6+75+150+150+30=411 ways. - 10 years agoHelpfull: Yes(5) No(7)
- We assume that all the toffees are similar. Then Number of ways are
(n+r-1)C(r-1)
. Here A + B + C + D + E = 6
Here r = 5, n = 6
Number of ways = (6+5-1) C(5-1)
=10C4
=210 ans
" If all the toffees are different, then each toffee can be distributed to any of the five. So total ways are
5^6 " - 6 years agoHelpfull: Yes(3) No(0)
- 10c5=252 ways..
- 10 years agoHelpfull: Yes(2) No(1)
- there are 720 ways.
since there r 6 toffes which r distributed btwn 5 people,it means 6c5 * 5c4 * 4c3 * 3c2 * 2c1 = 720 - 10 years agoHelpfull: Yes(2) No(1)
- @ could you explain how the formula is formulated?
- 10 years agoHelpfull: Yes(1) No(0)
- 6C5=6C(6-5)=6C1
=6x5x4x3x2x1
=720 - 10 years agoHelpfull: Yes(1) No(7)
- n=6
r=5
n+r-1 6+5-1

- We assume that all the toffees are similar.
Then Number of ways are (n+r−1)Cr−1(n+r−1)Cr−1.
Here A + B + C + D + E = 6
Here r = 5, n = 6
Number of ways =(n+r-1)C (r-1) = (6+5-1)C(5-1)= 210 .
If all the toffees are different, then each toffee can be distributed to any of the five That case total ways are 56.

- no of ways to select 5 toffees = 6C5 => 6 ways
no of ways each person(5) gets one toffee at least from the selected toffees = 5!
total no of ways = 6*5! => 720
now the last one can be given to anyone among the 5 persons hence total no of ways = 720*5/2= 1800 ways
