char,
What's the probability of 2, 3, 4 and 5 persons striking TOTO if
6 million combinations are bought? 
Is the probability higher than 1 person?
Cause every year you see them announcing so many winners.

If I can recall correctly, the total number of people striking
the top prize for the CNY draw each year is on average 5-8
persons. Each winner will on average walk away with a million
plus.
As for your questions on probability, you should be asking the
math tutors in the forum.
Do I look like a math geek to you?
