Rant time.... ;-) What's with these stupid "X in Y" numeric expressions that the dumb media insist on continuing to heap on the world ? Why not consistently use a standardised means of comparison. Like, I don't know .... percent. Or "X in 100" if you think your newspaper/blog/website readership are too dumb to know what the % symbol means. The clue's in the name FFS ... per... cent ... that's what its there for !
You can't have a fraction of a person. The probability of having .65 out of 100 people working for Amazon is zero, no matter which 100 people you select. 1 out of 153 can at least happen.
In this case, the BPN for working at Amazon is 107 (assuming everyone in the group is a worker).
