Question

A and B in a sample space S. Assume that Pr[A]=0.6, Pr[B]=0.5, and Pr[A∩B]=0.3.
(3) Pr[A′∩B′]=

Answer 1

ok first off you need to know that
\[A'\cap B'=(A\cup B)'\]

Answer 2

ok

Answer 3

then \[P((A\cup B)')=1-P(A\cup B)\]

Answer 4

and finally
\[P(A\cup B)=P(A)+P(B)-P(A\cap B)\] you have all those numbers

Answer 5

okay I will try it

Answer 6

so is the answer .2

Answer 7
