Answer:
In a betting game, you have a bag with red and blue balls. It has a total of 10 blue and 5 red balls. You take randomly 4 of them, one by one (without replacement). If you get more than 1 red balls you win 10 $
Is obtaining 1 or more red balls a dependent or independent event?
It's dependent, if you have 15 balls, and only 5 are red, then the probability of getting a red on the first try is 5/15. Assuming you do not get the red ball, in the second attempt the probability will be 5/14 ... That is, the probability of obtaining a red ball depends on the color of the ball that you have previously obtained.
You roll a dice 10 times and count the number of 5 you get.
Is obtaining 4 by 5 a dependent or independent event?
It's independent
The probability of obtaining a 5 when rolling a die will always be 1/6. Therefore, the probability of obtaining a 5 does not depend on you having obtained it before.
