Thanks Plato, Please let me know if these are correct. Also it looks like its asking for a probabilistic expression, am I wrong?

b. (AnBnC') U (AnB'nC) U (A'nBnC')

c.Is this a union of part a. and b. ?

d. (BnCnA')

Thanks please let me know if these are correct - Feb 10th 2013, 03:19 PMPlatoRe: Please need help with probability question before exam tmw
