Question 1070400: For the given pair of events A and B, complete parts (a) and (b) below.
A: A marble is randomly selected from a bag containing 2020 marbles consisting of 1 red, 1616 blue, and 33 green marbles. The selected marble is one of the green marbles.
B: A second marble is selected and it is the 1 red marble in the bag.
a. Determine whether events A and B are independent or dependent. (If two events are technically dependent but can be treated as if they are independent according to the 5% guideline, consider them to be independent.)
b. Find P(A and B), the probability that events A and B both occur.
Question : The probability that events A and B both occur is
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! The two events are technically dependent but are treated as independent because 33<5% of 2020. Picking the green marble for all practical purposes does not affect the chances of picking a red marble.
The joint probability is 33/2020 (I assume there are other marbles in the bag)*(1/2019)
=8.09 x 10^(-6)
