Question 655222
5 names need to be drawn from a pool of 10 and they are done so by putting them in a bag and using a blind draw. 
My question is - are the chances the same whether the blind draw is one name at a time, until 5 have been drawn, or drawing all 5 at once. 
----
5 at a time: 
# of possible outcomes: 10C5 = 252 unique groups of 5 names
# of ways to win: 1 group of 5 names
P(choose correct 5 from 10) = 1/10C5 = 1/252 = 0.003968...
------
One at a time:
1st good: 5/10
2nd good: 4/9
3rd good: 3/8
4th good: 2/7
5th good: 1/6
P(5 correct names) = (5*4*3*2*1)/(10*9*8*7*6) = 1/10C5 = 0.003969...

----
The results are the same.
Cheers,
