probability of independent and dependent events (6.2)
simple learning pro
if we randomly select two marbles from this box, what is the probability of drawing a green marble and then a blue marble, without replacement?
first event
p(green) = 7/10
= 0.7
second event
p(blue) = 3/9
= 0.33
of the first event affected the probability of the second event now
multiple - choice question
what type of event is this?
independent event
dependent event
rewatch

Explanation:

In independent events, the occurrence of one event does not affect the probability of the other. Here, when selecting marbles without replacement, the first - event (drawing a green marble) changes the composition of marbles in the box, thus affecting the probability of the second event (drawing a blue marble). So it is a dependent event.

Answer:

dependent event
