Dear r users,

I have 4 variables x1,x2,x3,x4 and each one has two levels, for example Y
and N.

For x1: prob(Y)=0.6, prob(N)=0.4;
 For x2: prob(Y)=0.5, prob(N)=0.5;
For x3: prob(Y)=0.8, prob(N)=0.2;
 For x4: prob(Y)=0.9, prob(N)=0.1;

Therefore, the sample space for (x1, x2, x3, x4)={YYYY, YYYN, YYNY,......}
(16 possible combination) and the corresponding probabilities are
{(0.6)(0.5)(0.8)(0.9), (0.6)(0.5)(0.8)(0.1), (0.6)(0.5)(0.2)(0.9),...}
I want to create a matrix includes all possible outcomes and the
corresponding probabilities.
That is

A=
YYYY  (0.6)(0.5)(0.8)(0.9)
YYYN  (0.6)(0.5)(0.8)(0.1)
YYNY (0.6)(0.5)(0.2)(0.9)
   .            .
   .            .
   .            .

Any efficient way to do this?

Thanks,

Kate
