Yes , it’s true. In a known-plaintext attack (kpa), the cryptanalyst can only view a small portion of encrypted data, and he or she has no control over what that data might be.
The attacker also has access to one or more pairs of plaintext/ciphertext in a Known Plaintext Attack (KPA). Specifically, consider the scenario where key and plaintext were used to derive the ciphertext (either of which the attacker is trying to find). The attacker is also aware of what are the locations of the output from key encrypting. That is, the assailant is aware of a pair. They might be familiar with further pairings (obtained with the same key).
A straightforward illustration would be if the unencrypted messages had a set expiration date after which they would become publicly available. such as the location of a planned public event. The coordinates are encrypted and kept secret prior to the event. But when the incident occurs, the attacker has discovered the value of the coordinates /plaintext while the coordinates were decrypted (without knowing the key).
In general, a cipher is easier to break the more plaintext/ciphertext pairs that are known.

Answer:
harris_poll_ranking = int(input("Enter team's Harris Poll ranking [1 - 2,850]: "))
coaches_poll_ranking = int(input("Enter team's Coaches Poll ranking [1 - 1,475]: "))
computer_ranking = float(input("Enter team's computer ranking [0 - 1]: "))
harris_poll_score = harris_poll_ranking / 2850
coaches_poll_score = coaches_poll_ranking / 1475
bcs_score = harris_poll_score / 3 + coaches_poll_score / 3 + computer_ranking / 3
print(bcs_score)
Explanation:
*The code is in Python.
Ask the user to enter the harris_poll_ranking as int, coaches_poll_ranking as int and computer_ranking as float
Calculate the harris_poll_score, divide the harris_poll_ranking by 2850
Calculate the coaches_poll_score, divide the coaches_poll_ranking by 1475
Calculate the bcs_score, harris_poll_score, coaches_poll_score and computer_ranking by 3 and sum them
Print the bcs_score
