the reason you don't just add them to be 10% is because -
If there were 20 chicks, all with 5% chance of blowing you...that does not mean there is 100% chance of a bj (it should tho misc, it should.)...there has to me some room for error there.

Let's say Mindy, Sarah, and Betty all have 5% chances of blowing you... Chances you get blown today are:
Sarah + Mindy + Betty - Sarah and Mindy - Sarah and Betty - Sarah Mindy and Betty
Point is, with two people, addition/subtraction is the way to go. As you add more girls, then you can use those autistic formulas

Law man to the rescue: why it's not 5%

The big circle represents your universe: either you will get blown or you won't
The gray represents the chance you don't get blown
The red, the chance you get blown by Mindy. The blue, the chance you get blown by Sarah. The purple, the chance you get blown by both.
Let's say it's 9AM, and you're at the office. Mindy isn't in yet, and Sarah isn't in yet. The chance you get a blow job today (either Sarah or Mindy will come in and blow you) is 9.75%.
Let's say now it's noon, and Mindy called, saying she won't be coming in today. Now the chance you get a blow job today (Sarah will come in and blow you) is 5%.
But if you have no prior information, either Sarah or Mindy can polish your knob, so your chance of a blowjob is greater than 5%.

But this example in the OP is two separate events, and they should be summed (not multiplied). So you have the first event with a probability of 1 in 20, and a second event with a probability of 1 in 20.
1/20 + 1/20 = 2/40 = 5%
For you guys making the mistake of multiplying, here's why that is wrong. If we wanted the % chance of getting consecutive bj's, we'd multiply as the events are dependent on each other. The chance of getting a bj from the first girl, and also the second would be 1/20 * 1/20

Just do a weighted average.
(5% chance of bj from one slut+50% weight)+(5% chance of bj from other slut+50% weight)
=5%
(5% chance of bj from one slut+50% weight)+(5% chance of bj from other slut+50% weight)
=5%

I wouldn't be able to tell you the exact answer like the other guy, but common sense tells you 25% chance is ridiculous, and that it has to be above 5%. If you have a 5% chance of getting a blowie from one sloot, and also a 5% chance with another, your chances go up the more you add sloots. If you have 10 girls that want to zuk your dik with a 5% chance each, obviously your chances of getting a single BJ is higher than 5%. That said it's not going to be quite 10% either, since the probability doesn't simply double.

What I find amazing is all of the people calling others potatoes and most of them had the wrong answer.

Brb let's say both girls have a 50% chance. Brb that means there's a 100% chance according to your logic

The chances you get a blowjob today are:

You subtract .25% because if Sarah blows you, whether or not Mindy also blows you, you got your bj for the day. And likewise, if Mindy blows you, whether or not Sarah also blows you, you got your bj for the day.

(Girl1 BJ) 5%* (Girl 2 NoBJ) 95% = 4.75%
(Girl1 No BJ) 95%* (Girl 2 BJ) 5% = 4.75%
(Girl1 BJ) 5%* (Girl 2 BJ) 5% = .25%
4.75% + 4.75% + 0.25% = 9.75%
(Girl1 BJ) 5%* (Girl 2 NoBJ) 95% = 4.75%
(Girl1 No BJ) 95%* (Girl 2 BJ) 5% = 4.75%
(Girl1 BJ) 5%* (Girl 2 BJ) 5% = .25%
4.75% + 4.75% + 0.25% = 9.75%

In this universe there are 4 possible outcomes: Sarah BJ, Mindy BJ, Sarah and Mindy BJ, and no BJ. The question asks what are the chances you get at least one BJ for the day, that is, either Sarah or Mindy gives you a blowjob. If both give you a blowjob, that doesn't affect the equation because all you need is one BJ. So you gotta subtract the chances that both give you a BJ. So the equation is, 5% (sarah bj) + 5% (mindy bj) - .25% (sarah and mindy bj).
Method 2: Sarah BJ and no Mindy BJ + Mindy BJ and no Sarah BJ + Sarah BJ and Mindy BJ
Again, the question asks what are the chances you get at least one BJ for the day, that is, either Sarah or Mindy gives you a bj. Here you're adding all the possible ways for you to get a blowjob for the day. Sarah could give you a bjwith Mindy not giving you a BJ; Mindy could give you a bjwith Sarah not giving you a bj; and both sarah and mindy could give you a bj. Here the both is added at the end because the first two terms are limited: they only include the chances one of the girls give you a bj. The first two terms weren't so limited in the first method.
