The 1st one is very clear. Thank you. What formula was used for the 2nd one? That's the ine I had the most trouble with. Thanks again!

The formula for the amount of ways choosing n objects from a set of k objects is nCk (read "n choose k") = n!/((n-k)! * k!). Also, 0.00039 = 0.039%

Ok thank you so much for the help!
The answer is accepted.
