Statistics and Probability Question/ Give The Mean
Suppose that A and B are independent events such that P (A) =0.10 and P (/B) = 0.60

Find P (A n B) and P (A U B)

P ( A n B) =

P (A U B) =

Hello thank you for your help with this problem I appreciate it very much.

If $H~\&~K$ are independent events then
$P(H\cap K)=P(H)\cdot P(K)$
$P(H\cup K)=P(H)+P(K)-P(H)\cdot P(K)$.

I have never seen the notation $P(/B).$
