Final answer:
To solve the probability question correctly, we need to know the size of the applicant group being reviewed. With the group size and the percentage of women applicants, we could apply a binomial probability model to calculate the asked probability, but this critical information is not provided.
Step-by-step explanation:
The question asks for the probability that the number of women in a group of applicants is less than or equal to 15 when 20% of applicants are women. To calculate this probability, additional information is needed, such as the total number of applicants in the group being reviewed. Without the information on the size of the group, we cannot provide a specific numerical probability.
If we had the group size, we could set up a binomial probability scenario given that each applicant being a woman is an independent event, and we're interested in the probability of 15 or fewer successes (women chosen) in a series of trials (applicants reviewed).
Considering that critical information is missing, we cannot determine whether the provided answer choices a, b, c, or d are correct.
