Question 14 sur 17
You roll a fair six-sided die once. What is the probability of rolling a 2 or a 5? Voir la réponse Réponse: C. 1/3
You cannot roll both at once, so the events are mutually exclusive. Add: 1/6 + 1/6 = 2/6 = 1/3.
Question 15 sur 17
You flip a coin and roll a six-sided die. What is the probability of getting heads and a 6? Voir la réponse Réponse: A. 1/12
The events are independent, so multiply: 1/2 × 1/6 = 1/12.
