Respuesta :

We have the following data:

P(V) = 0.85

P(S) = 0.96

P(V and S) = 0.82

We can use the rules of addition to find P(V or S) as:

[tex]\begin{gathered} P(V\cup S)=P(V)+P(S)-P(V\cap S) \\ P(V\cup S)=0.85+0.96-0.82 \\ P(V\cup S)=0.99 \end{gathered}[/tex]

Answer: The probability that a randomly chosen ice cream was vanilla or was ordered on a Sunday is 0.99.
