Suppose a 5-bit message is transmitted from a source to a destination through a noisy channel. The probability that a bit of the message gets flipped during transmission is 0.01. Flipping of each bit is independent of one another. The probability that the message is delivered error-free to the destination is ______ . (rounded off to three decimal places)

Attempted by 111 students.

Show answer & explanation

Correct answer: 0.949 to 0.952

Each bit has:

  • Probability of flipping (error) = 0.01

  • Probability of not flipping (correct) = 0.99

Message length = 5 bits
Bits flip independently.

To receive the entire 5-bit message error-free, all 5 bits must be correct:

P(no error)=(0.99)5

Compute:

0.995=0.9510  

Rounded to three decimal places:

0.951
