Question: In a bit - oriented link - layer protocol, the start and end of a frame are each marked by an 8 - bit flag

In a bit-oriented link-layer protocol, the start and end of a frame are each marked by an 8-bit flag sequence. All the other bits in the frame are used to generate a 32-bit CRC, which is transmitted just before the end flag. If the probability of an error in any received bit is 0.000015, and the total length of the frame, including flags, is 2,201 bits, what is the probability of an error being detected in the frame?
