Question
For two events $A$ and $B$, let $P(A)=0.4, P(A+B)=0.7$ and $P(B)=p$. For what value of $p$ are $A$ and $B$ (i) mutually exclusive, (ii) independent?
Step 1
4$, $P(A \cup B)=0.7$ and $P(B)=p$. We need to find the value of $p$ for two conditions: (i) when $A$ and $B$ are mutually exclusive, and (ii) when $A$ and $B$ are independent. Show more…

'Let A and B be two events. Suppose that P(A) = 0.4, P(B) = p and P(AU B) = 0.8 For what value of p will and B be mutually exclusive? For what value of p will A and B be independent?'
A- Let A and B two events such that P(A) = 0.4 and P(A or B) =0.7. Find P(B) if A and B are independent. B- Let A and B two events such that P(A) = 0.6 and P(A or B) =0.8. Find P(B) if A and B are mutually exclusive events.
Let A and B be two independent events with P(A) = 0.4 and P(A∪B) = 0.64. What is P(B)?
