Determine the numbers for lottery and how many will be drawn

Hi.
I need to randomly select numbers, as determined by the user.
actually not quite generate a random number, but preexisting raffle numbers from a list, that these numbers will be informed, as well as how many of them will go to lottery.

1 is informed that the figures are: 14, 25, 38, 51, ​​59, 63, 65, 70, 84, 91 and 99.

2 How many of this group will be randomly selected.

These are the criteria to be followed.

To select a random member of your group:

=CHOOSE(RANDBETWEEN(1,11),14,25,38,51,59,63,65,70,84,91,99)

Hi.
I am grateful for your response that helped me a lot!
Is there any solution to eliminate repeated?

Do you want to pick a second value without repeating the first?

Hi.
by pressing the F9 key, I have some numbers that are repeated.
70 -->repeats
25
70 -->repeats
59
91
63 -->repeats
38 -->repeats
51
63 -->repeats
38 -->repeats
38 -->repeats

To avoid repeats, we need to keep track of which items have already been picked. We will do this in column B. In B1 enter:

=RANDBETWEEN(1,11)

In B2 we enter the array formula:

=LARGE(ROW($1:$11)*NOT(COUNTIF($B$1:B1, ROW($1:$11))), RANDBETWEEN(1,11-ROW(B1)))

because it is an array formula, it must be entered with CNTRL-SHFT-ENTER rather than just the ENTER key.

Copy B2 and paste from B3 thru B11.

Now in A1 enter:

=CHOOSE(B1,14,25,38,51,59,63,65,70,84,91,99) and copy down thru A11

A1 is the first pick; A2 is the second pick; etc.

hello Jakobshavn

I want to thank you for your help, thank you
I still have to do some testing, but I'll mark as solved!

thank you very much!!
