Jada practices the violin for the same amount of time every day. On Tuesday she practices for 35 minutes. How much does Jada practice in a week?

We can determine this by looking at the odds of getting an even number on the second spin given an even first spin and an odd first spin. If you look at both situations, there is still a 50% chance of getting an even number on the second spin. Given this fact, we can tell that the first spin doesn't affect it and therefore they are independent events.
