You can put this solution on YOUR website! A bag contains 15 chips-five are blue, four are red, and six are white. If four are picked one at a time without replacement, what is the probability that at least one red chip is picked?
----
P(at least one red) = 1 - P(no red)
---
= 1 - 11C4/15C4

= 1 - 0.2418

= 0.7582
