Indeed, it’s 6.12 *10^-6 putting it in percentage, that would be 6.12 * 10^-4% or in decimals 0.000612%. I missed one zero. I’ll correct that. Thanks for checking and letting me know.4/46*3/45*2/44*1/43 is 24/3,916,440 = 0.00000612% of 1 in 163,185
You missed a few Zeros to the left
Though, btw, you have a bit too many zeroes after putting the %.
