Question

Tell whether the events are independent or dependent. Explain.
selecting a compact disc from a storage case and then selecting a second disc without replacing the first.

Answer 1

well independent means if the result of the other event has no effect on the other

Answer 2

Start with for example 10 in the case
then chances of getting disk A is 1/10
However when you go for the second one, the chances of getting a particular disk are 1/9
so the second trial depends on the first one.
