You can put this solution on YOUR website! in a basket there are 25 red ball, 25 white balls, and 25 blue balls the probability of drawing 2 red balls in a row is 1/3 . true or false .
----
If balls are replaced after drawing, P(red and red) = (1/3)(1/3) = 1/9
---
If balls are not replace after drawing, P(red and red) = (25/75)(24/74)
===================
Neither of these answers is 1/3
===================
Answer: false
