Question

Say in plain language what the event$“AorB”is.WhatisP(AorB)$?

Short answer

$P\left(AorB\right)=P\left(A\right)+P\left(B\right)$occurrence and probability.

Step-by-step solution

Step 1. Given Information 

P (A or B) = P (A ∪ B)

P (A or B) = P (A) + P (B)

Step 2. Concept Used   

Definition of the probability addition theorem: Assume $A$and $B$are two events in a random experiment, and you want to know whether $A$or $B$has a higher likelihood. Then apply the probability addition theorem.

Step 3. Calculation    

Assume that A and B are two random events in a random experiment. utilise the probability addition theorem That's $$\begin{gathered} P(AorB)=P(A\cup B) \\ P(AorB)=P\left(A\right)+P\left(B\right)-P(A\cap B) \end{gathered}$$for you.

If the occurrences $A$and $B$are mutually exclusive.

Then $$\begin{gathered} P(A\cap B)=0 \\ P(AorB)=P\left(A\right)+P\left(B\right) \end{gathered}$$

As a result, the event and the likelihood of$P\left(AorB\right)=P\left(A\right)+P\left(B\right)$
