A new chewing gum has been developed that is helpful to those who want to stop smoking. If 60% of those people chewing the gum are successful in stopping smoking, what is the probability that in a group of 4 smokers using the gum at least one quits smoking?
well, 60% of four people is...2.4 Out of 20 people, 12 people will quit smoking.

The probability that none of them quit is (.4)^4 = 0.0256,
so the probability that at least one quits is 97.44%
