Expert Solution
Step 1
Independent events are those events whose occurrence is not dependent on any othe event. For example, if we flip a coin in the air and get the outcome as Head, then again if we flip the coin but this time we get the outcome as Tail. In both cases, the occurrence of both events is independent of each other.
