If you wanted to know the probability of getting either outcome A or B, and they are mutually exclusive, which equation would you use? Pr[A or B] = Pr[A] - Pr[B] Pr[A or B] = Pr[A]/Pr[B] Pr[A or B] = Pr[A] + Pr[B] Pr[A or B] = Pr[A] x Pr[B]

If you wanted to know the probability of getting either outcome A or B, and they are
mutually exclusive, which equation would you use?
Pr[A or B] = Pr[A] - Pr[B]
Pr[A or B] = Pr[A]/Pr[B]
Pr[A or B] = Pr[A] + Pr[B]
Pr[A or B] = Pr[A] x Pr[B]
