Question
independent and dependent event

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
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.
