Looking into your post, I do not understand clearly, what is your problem.


You just have the answer to (b), and this answer is CORRECT.




The answer to (c) is OBVIOUS:  the probability = 1/2035820.

B) A lottery has 52 numbers. In how many different ways can 6 numbers be selected ?
Ans 52C6 = 20358520
-----------------
The 1st choice is 1 of 52
Then 1 of 51, etc
---> 52*51*50*49*48*47
But, any of the numbers can be picked the 1st, 2nd, ... 6th time.
---> 1*2*3*4*5*6 ways to choose any combination = 720 ways.
-----------
52*51*50*49*48*47/720 = 20358520 ways.
-------------------------
C) If you bought one ticket in the lottery drawing in (b) above what would be the probability that you would win the big lottery?
----
It's 1 out of 20358520 ways.
==================
Or, as my sister-in-law says: it's 50-50. You either win, or you don't.
