let's say steko is equally obedient to each of them and their behaviours:
the possible set is {(shoop(gay), beeeh(racist), sidey(rapist), steko(gay)), (shoop(gay), beeeh(racist), sidey(rapist), steko(racist)), (shoop(gay), beeeh(racist), sidey(rapist), steko(rapist))}
Each tuple has 6 possibilites which makes up to 18 tuples with 6 tuples where steko is racist.
The probability for steko being racist is 6/18 or ~33%
But that calculation is of little value since we all know that Steko is racist and being racist doesn't exclude being rapist either. Depending on the definition of being racist it might be as probable that he is gay, too.
If we take this into account the probabilty for steko being racist and rapist is as high as him being rapist and gay, there is still probability of him being rapist, racist and gay, but less probability of being gay and racist.
Therefore the probabilty of Steko being rapist is the highest, wheresas him being racist or gay is a little lower.
