independent events
what marble you get is independent of whether the coin is heads or tails, if this is the only information given
if the coin toss and marble grab are done randomly.
But there are scenarios where they might be dependent. Such as somone has a bet that the two events are Tails and a Green Marble. The dishonest coin flipper sees the Tails and dishonestly looks for a Green Marble to help his friend/accomplice win the bet
