Question 565141
There are 4 different seeds, 3 yellow and one green. What is the probability that 3 seeds chosen at random will include at least one yellow seed? 
---
P(at least one yellow) = 1 - P(no yellow)
---
CommentI if you choose 4 seeds you cannot avoid having some yellow.
Ans: P(at least one yellow) = 1
