Problem 1
Jada rolls one standard number cube, then she rolls another standard number cube.
- What is the probability that she rolls a 5 on both number cubes?
- What is the probability that the second roll is a 5 under the condition that the first roll is a 6?
- What is the probability that the second roll is a 5 under the condition that the first roll is a 5?
- What is the probability that the second roll is not a 5?
- What is the probability that the first roll is a 5 and the second roll is not a 5?
Problem 2
A board game has 4 player tokens to choose from. Three of the tokens are animals, and the fourth token is a car. Kiran randomly selects one token, then Mai selects her token. What is the probability that Mai selects the car token under the condition that Kiran selects an animal token?
