Question

if e and f are disjoint events, then p(e or f)= p(f) p(e and f) p(e) p(e)+p(f) p(e)+p(f)-p(e and f)

Explanation:

Step1: Recall the formula for mutually - exclusive events

For mutually - exclusive events \(E\) and \(F\) (events that cannot occur at the same time), the probability of \(E\) or \(F\) occurring is given by the formula \(P(E\cup F)=P(E)+P(F)\).

Answer:

\(P(E)+P(F)\)
