Hi,
*Note: probablity that at least one is green is: 1-probability that none are green.
85% are other than green.
.
probability that none are green when picking three
P+=+1%2A%28.85%29%5E3%2A%28.15%29%5E0+=+.614
.
probablity that at least one is green when picking three
1- .614 = .386
.
38.6% chance at least one will be green.
