Question 868496
There are {{{33}}} multiples of {{{3}}} from {{{1}}} to {{{100}}}.
There are {{{25}}} multiples of {{{4}}} from {{{1}}} to {{{100}}}.
There are {{{16}}} multiples of {{{6}}} from {{{1}}} to {{{100}}}.
There are {{{14}}} multiples of {{{7}}} from {{{1}}} to {{{100}}}.
That means {{{33+25+16+14=88}}} outcomes are wins for the players.
So 12 outcomes are wins for the house.
{{{P(House win)=12/100=3/25}}}
If I was you, I'd choose 3 or 7.
