you mean losing on the come-out roll, what can be called one hand, in 100 hands?

Offhand I'd estimate at better than 80%.

Poorly formed question. For example, you haven't even said what kind of wager you are making. I'll assume you are referring to making a pass line bet. Next, you aren't clear whether you mean the probability of losing at least once, losing every time, or the probability on each pass line bet.

So here's my answer: Each pass line bet has 1 chance in 36 (2.777%) of losing on a come out roll of craps 2. Doing that at least once in 100 come out rolls has a probability of p=1-(35/36)^100=94.022%. But that might not be what you are trying to ask.
