**Reiny**, Saturday, October 9, 2010 at 9:52amP(S and M) = P(S) + P(M) - P(S or M)

= .3 + .35 - .45

= .2

You could now make a Venn Diagram with two overlapping circles called S and M

Enter .2 into the overlap ( the P(S and M) )

since S must be .3 and .2 is already accounted for, the part of ONLY S would be .1

in the same way the part of M only would be .15
