Question

A journal polled its readers to determine the proportion of wives who, if given a second chance, would marry their husband. According to the responses from the survey, 61% of wives would marry their husbands again. Suppose a random and independent sample of n = 17 wives was collected. Define the random variable X as the number of the 17 wives who would marry their husbands again. Then we know X is a binomial random variable. How many of the 17 wives sampled do we expect to say they would marry their husbands again

Answer 1

is this a binomial cdf ?
