According to the responses from the survey, 72% of wives would marry their husbands again.
Suppose a random and independent sample of 5 wives was collected. Define the random variable X as the number of these wives who would marry their husbands again. Use the binomial distribution to find the probability that at most 4 of the wives sampled said they would marry their husbands again.

"At most, 4" is the same result as 1-P(5), i.e. 1 minus the chance that all 5 said yes. Which makes the math simpler.
1-(.72)^5=1-.19349= .806508 (b)
