The proportion of party A supporters is 30%. What is the probability that if 5 voters at random are selected that all 5 are NOT supporters of party A?

Hi Since the probability that a person supports A is 0.3 , then the probability of a person NOT supporting A is $\displaystyle 1 - 0.3 = 0.7 $ So, for 5 random people not supporting A we get: $\displaystyle (0.7)^{5} \approx 0.168 $
Thanks a lot. I was debating whether that or 0.7 * 5. I appreciate it
