Question

Q and R are not mutually exclusive events. If P(Q) = 5/8, P(R) =1/8 and P(Q and R) = 1/32, find P(Q or R).

(a). 5/32
(b). 23/32
(c). 3/4

Answer 1

so simple
P(Q or R) means P(Q U R)
P(Q and R) means P (Q intersection R )
so just use this formula
P(Q or R) = P(Q)+ P(R) - P (Q and R)
and get the answer
