Question 393159: in a recent poll 70% of the surveyed said that they will not go away on vacation this year. if three people are randomly selected, what is the probability that all 3 will not go away on vacation this year Answer by ewatrrr(24785) (Show Source):
Hi
Note: The probability of x successes in n trials is:
P = nCx* where p and q are the probabilities of success and failure respectively.
In this case p(not going on vacation)= .70 and q = .30
nCx =
P(3 selected not going on vacation) = (.70)^3 = .343
