Seems to me just like drawing from a pack of cards without replacement.
p = 136/500 * 135/499 * 134/498 = 0.0198
A poll asked 500 adults if they thought Ontario should produce more, less or maintain current production of ethanol.
-160 people responded "more ethanol production"
-136 people responded "less ethanol production"
-155 people responded "maintain current production level"
-49 people had no opinion
Three people are selected at random from this sample
What is the probability that all 3 responded "less ethanol production"?
