Please show all the calculations

Please answer all three question this would be much appreciated. Thank you so much

7.4 With the ECB mode if there is an error in a block of the transmitted cipher text, only the corresponding plaintext block is effected. However, in the CBC mode, this error propagates. For example, an error in the transmitted c1 (figure7.4) obviously corrupts p1 and p2.

a. ARe there blocks beyond p2 affected.

b suppose there is a bit error in the source version of p1. Through how many ciphertext blocks is this error propagated? What is the effect at the receiver?

7.5 Is it possible to preform encryption operations in a parallel on multiple blocks of plaintext in CBC mode? How about decryption?

7.10 In discussing the CTR mode, it was mentioned that if any plaintext blocks that is encrypted data using a given counter value is known, then the output of the encryption function can be determined easily from the associated cipher text block. SHow the calculation.
