Answer:
11.43% probability that the first three lined up in the interview are all females if the order is chosen at random
Step-by-step explanation:
Initially, there are 7 applicants, 4 of which are female. So the probability of the first person lined up in the interview being a female is 4/7.
Now we suppose that a female has been chosen, which means that there are 6 applicants, 3 of which are female. So the probability of the second person lined up in the interview being a female is 3/6.
We suppose that the second choice was also a female. Now there are 5 applicants, 2 of which are female. So the probability of the third person lined up in the interview being a female is 2/5.
What is the probability that the first three lined up in the interview are all females if the order is chosen at random?
