I_luv_cydy,
Normaly the binomial distribution is used to make the calculations in the case of S-C as the outcome is either the patient survives or doesn't:
As we have two groups this is sometimes called a two group independent test. Some information below:

A more formal approach is here with info in the p-number:

You can build your model (in excel for example), or use a statistical package (like S.A.S.). There are websites that do the calculations, I take it you want to understand where the number comes from
Let's hope today we continue in an upswing so we can celebrate 4th July in style.

The binomial distribution model allows us to compute the probability of observing a specified number of "successes" when the process is repeated a specific number of times (e.g., in a set of patients) and the outcome for a given patient is either a success or a failure.
