Answer:
Independent events
Step-by-step explanation:
Given that:
Ramiro draws a marble from a jar without replacement and then flips a coin
Let be the event that Ramiro draws a marble without replacement and;
Let be the event of flipping a coin.
Let's have an analogy so that we can better understand the concept of independent and dependent events.
Consider a random experiment in which a marble is drawn from a jar without replacement and a fair coin is flipped together.
The event does not in any way affect the event
of a head or a tail showing up in a flip of a coin.
Therefore, we say that and
are independent events.
Suppose the event affects or influence the event
, then we can say they are dependent events.
