The question is..
A, B and C are events of a sample space headphones(cant find symbol). Obtain expressions for each of the following events:
a. exactly one occurs;
b. exactly two occur;
c. at most two occur
d. both B and C occur but not A
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. ?
Thanks please let me know if these are correct
