In a colony of 1,500 lemmings, exactly 30 lemmings are variegated. If one lemming is chosen at random from the colony, what is the probability that it is not variegated?

Continue

There are 1,500 lemmings and only 30 of them are variegated. That means that nearly all the lemmings are not variegated. So the probability of picking a non-variegated lemming is very high.

The first three probabilities are small, so you can eliminate them right off. Here it might be easier to calculate the probability that a lemming is variegated, and subtract that from 1 to find the probability that a lemming is not variegated. So, the probability that a lemming is variegated is:

.

And that makes the probability that a lemming is not variegated .
