Question 592077: find the probability of this set of an independent event.. I have a bag of 9 black checkers and 6 red checkers, I draw a red checker, I replace it and draw another red checker. Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! 9+6=15
6/15=2/5 probability of the first checker being red.
6/15=2/5 probability of the second checker being red.
2/5 * 2/5 = 4/25 probability of them both being red.
